Update - after doing a chargeback with the bank....
I've got all £8000 back !!!
Good news and a story many could learn from.
These types of places offer very little value for money and will try and rip customers off.
I've been to a few strip club's, in the UK (every time I've been a guest of other people and the only reason I've gone) strip club over charge for drinks and other things on offer. Never taken a card into one as it's to risky, IMO. I only take ca$h in with me and that way, I can only spend what I have. To this day I've always come out with ca$h, much to the dismay, of that strip club or it dancers. I prefer to spend that ca$h on a punt.
I remembered being a guest and one of the party, left his card behind that bar to pay for drinks. Bottles of J/D £110 etc, not what I would do.
Places people are not sure about but have taken a cards into. Should really consider, using low limit credit or pre paid cards that are not linked to bank account (often don't have a name on it). Most banks these days issue debit cards with current accounts. No reason not to, have several that have a set amount of money in. Thus if a scam happens, its not a massive loss, if you can't get it back.
