If an event or tournament has a fee, a fee card on its page shows your
share (the fee split between players — tournament fees split in half per
partner).
Pay by card (Stripe) or PayPal if the club accepts it; some clubs also
take cash at the desk and mark you paid.
Club credit is money you hold at one club, from a cancellation or from a
refund the club chose to give as credit. It is spent automatically against
your next fee there.
Money goes directly to the club.
If the club cancels, it decides what happens to money already paid: a
refund to your card or PayPal, club credit, or — for a late
cancellation the players caused — the club may keep it. You are told
either way. If you cancel your own paid booking you always get club credit.
Once you have paid you can't simply leave — but you can list your seat
and hand it on. A club can't remove a paid player without refunding first.
Clubs can flag non-payers; some clubs block flagged players from booking
until it is cleared.
