Bartenders do their best to be fair during service and keep tabs on who walks up when, but when a bar is slammed, there are more don'ts than do's to follow. Don’t snap, whistle or yell at them; slam your hands down on the bar; wave money or a credit card; gesture obscenely; grab them; or stand in the service bar. Do make eye contact, give them a sympathetic smile or empathetic look, and above all, be ready with your order. "Know what you want; when the bartender turns to you and makes eye contact, the last thing you want to do is stutter and not know what you want. Most likely the bartender will skip you and move on to the next guest that [is] prepared," explains Saul Parada, a long-time bartender who manages Watts & Ward in Raleigh, North Carolina.
