The **prime time** of the event is **10:30 - 12:30**. That's when most people will be there. 2. When you enter the gallery, it's either on the right-hand side or left-hand side of its hallway, depending which entrance you take. 3. If you intend **to join past 12:00** (high noon), then there is no need to register. Just come and join! 4. **DON'T forget to cancel** if you can't join! 5. **Please, be respectful towards each other during the event.

Hello! This is a meet-up to play tennis from 2 pm to 4 pm on Sunday. Meeting is on the courts. The courts are booked under the name Jean-Marc. This event is for intermediate and advanced players and not organised for novice players or beginners. Please make sure to bring the exact sum of 11 € in cash. The event is non-commercial. This sum covers the cost of the courts reserved. The organizer is not there to make money out of you. Ladies are encouraged to join. If anyone wants to drop out, they should do it on Saturday morning, not on Sunday the day of the meetup, another wise it would be too late to find a replacement in time or to cancel a court in time with reimbursement. If you don't do this, you will be asked by the organizer to reimburse your participation fee. If this happens too late then those who have cancelled after Saturday morning will have to cover the extra cost for reserving the courts. In the past meetups, it happened too many times that we were an oneven number and because of that all those present had less fun to play. If you don't show up without giving a written excuse in time, the first future participation will be cancelled and you will be asked to reimburse the participation fee. If it happens too many times you will not be able to participate anymore. In case if we are an uneven number of players, then the last player (except the host of course who has to collect the money) can leave or persuade other players to play with him or her. Of course if the last player leaves, then he or she doesn't have to pay the participation fee. If this player leaves, he or she will be added on a future event by the host or organizer in the participation list if the player is far away in the waiting list. This is the advantage of leaving on a voluntary basis;-). We operate on the principle of Fair Play as we do not have umpires or referees. Any disputes or disagreements over line calls or scores should be resolved immediately on the court and, when agreement is not possible, the point or game should be replayed. To be able to replay the game, 3 players need to agree on that without manipulation of the one who disputes an entire game, anotherwise injustice could occur where in the end possibly the biggest cheater could win... This situation applies also, if the host or the organizer is involved. When one of the players still doesn't accept this compromise, then it should be reported (meetup message by preference) to the organizer or host of the meetup event. One of the consequences could be that the first upcoming event could be cancelled by the organizer for the player who doesn't comply with the compromise to play the point or the game again. If the same player does that again for a second time, then the person will see 4 of his next tennis meetups cancelled. If this happens a third time with the same player, then the player in question will be banned from all future tennis meetups with an exclusion as a final result. Whenever there is a big problem, it should be reported as well to the organizer of the group so he can, if necessary, take actions to improve the situation for all the players. Please also note that if you are the first on the waiting list, you will automatically be moved up to the attendance list if someone pulls out. So if you are on the waiting list and see that you cannot attend, please also change your status to not going. If you would like to organize a meet up either this week or next week please get in touch with me, my name is Jean-Marc. It will depend on your initiatives to create more tennis meetups per week.

A relaxed pool night and language exchange for curious, open-minded people in Brussels. Pool, drinks, and real conversation without the fake networking vibe. This is **not** a tournament and not a “watch one guy run the table” event. We rotate games, mix people, and keep it social. Use our whatsapp Chat also to RSVP and updates! https://chat.whatsapp.com/CArK9cobiSmCKRSKCGhFCJ ### **What to expect** * Casual pool * Rotations so everyone plays * **Language exchange**: EN/FR/NL/ES/IT (and whatever else shows up) Switch languages anytime, no pressure ### **Food** The venue is right next to **Dea’s Pizza**. During the night, feel free to grab a takeaway pizza and **eat it at Taverne Magnolia**. ### **Cost** * Everyone pays their own drinks and table time * If we share tables, we split costs fairly (1 game 1 Euro) ### **Safety and respect policy (non-negotiable)** We’ve had reports of creeps at other Brussels meetups bothering women. That does not happen at our events. * The host will actively keep an eye on the vibe, especially **women’s comfort and safety** * **No harassment, no sexual comments, no persistent flirting after a “no,” no invasive questions, no following people around** * If someone feels unsafe or uncomfortable, go to the host directly. The host will intervene. ### **Meet point** Meet inside near the pool tables at **Taverne Magnolia**. If you’re late, post in the event chat so rotations don’t start without you.
