I go regularly and I’ve managed to get lucky each time at least once.
Yes it’s pot luck, with punting you choose a young blonde with Big tits that offers OWO etc and pay your money. In a club it’s much different so it depends who is on there and there are no guarantees.
There can be a lot of waiting around, sometimes for hours, but as long as you know that and are prepared to wait it out, then all is good.
Be polite, non pushy, spotlessly clean and approachable and make conversation and you should have some success.
In my experience, single ladies are the vast minority, single men are 10 a penny for the ladies to choose from, but most of my fun has been where the husband has asked if he can watch me with his wife etc.
