1. Our happy hour special is 2-for-1 draft *draught* beer.
2. Would you like another round of drinks?
3. If a customer is "cut off", it means that he/she is not allowed to order any more drinks (because of drunkenness, bad behavior, etc.)
4. That'll be $5.50.
5. We don't have any draught beer. We only have bottled beer.
6. Shots of hard liquor (vodka, Jagermeister, etc.) are commonly referred to as shooters.
7. I would never water down a drink. I would lose my job if I did.
8. It's a bad idea to mix vodka with wine.
9. Smoking is not allowed anywhere inside the bar. You'll have to go outside to smoke.
10. Sir, please don't disturb the other customers.
