> I agree you don't tip tickets, but in the US tipping bartenders per drink is pretty standard. Actually, this kind of relates to the example in the article -- spending $100+ on tickets and food/drinks and only tipping $2. If the drinks only made up, say $20 of that, then a $2 tip is not unreasonable. That works out to 10% tip, which I think is acceptable for the amount of service provided.
