Roll Up, Roll Up, Fifty Dollars A Puke!!
In most places in the world, return the goods and you get a refund.
Return your drinks in Pennsylvania and it will cost you fifty bucks a time.
At El Azteca, a Mexican restaurant and bar near Pennsylvania University, any group of drinkers larger than six are required to sign a restrictive contract that lists a credit card number which can be used to pay for any damages incurred by inebriated clientèle. For every puking customer, a $50 fine is charged to the credit card.
Wouldn't it be far easier all round just to stop serving those patrons who appear to have reached their limit?
