Movies often depict bartenders dancing on bars or polishing glasses while listening to everyone’s problems. In reality, most are skilled professionals focused on providing great service. Even with good tipping and avoiding obvious mistakes, some polite-seeming habits can still annoy them. Here’s what to avoid and how to be a better customer.

Asking them to do a shot with you

Bartenders are working and often have rules against drinking on the job. They need to stay professional and focused during their shift. Instead, add the cost of the shot to their tip or offer to buy them a drink for after their shift. This way, you show your appreciation without putting them in an awkward position.
