No fucking way that's true.
oh its true alright...just came from there and they have the most retarded system.
when you enter a club, you will be given a cardboard card with all of the clubs drinks available (better clubs will give you a magnetic swipe card)
each time you buy a drink they will mark your card or swipe it with your drink order
(first time i was given a card i was like wtf is this??? i will lose this shit before the night is thru - if you lose it you have to pay $300 or so)
Anyway, your admission and everything is on that card and you pay 1 or 2 cashiers at the end in a heavily secured area (again, annoying as shit because after a night of drinking you just want to leave the bar, not queue up again)
in order to leave the bar, you have to present your paid receipt to security. that's the only way you can exit.
not sure why they use this system. i suspect in a place with high crime, it makes sense to keep all the money in one secure area, no bartenders fiddling with cash.
You also cant really keep track of how much you've spent as the night goes on and i have heard of incidents of bar staff adding drinks you didn't order to your bill.
Feel sorry for these people.
