3. $1 per drink
Up to 28 percent of bartenders surveyed said that $1 per drink is a pretty reasonable tip in most cases, but it depends largely on how much you are paying for your drinks. While $1 may be perfectly appropriate in establishments with relatively reasonable prices, a buck per drink may put you in the company of cheapskates in a more expensive setting. Tipping, as most people know, depends a lot on how much you are paying for the product or service you are purchasing.
