The bar is basically a stage
"As soon as you step behind the bar, all eyes are on you. Even people in the booths or people just passing by are interested in who's behind the bar: 'What're they feeling? What're they working on?' That can be at a cocktail bar or a dive bar.
"It's about how you carry yourself. It's about knowing that everything [you do] is watched. It's about your facial expressions, the energy you're giving off. Your personality. Obviously things like cell phone use or eating behind the bar or picking your nose, they're all definitely taboo. But understand that you're being watched, so fold that into your movement and attitude."
The job is all about the customer
"You have a job because people want to come and sit at your bar; they want to drink. Your livelihood is based on your guest. Understand that simple fact about bartending, and all these other points will make sense. You're there for every guest in the establishment, and especially every guest at the bar."
Taking care of the guests is a huge responsibility
"Alcohol service is something that should be taken seriously. [Good bartenders are always paying attention to] how much guests are drinking, how quickly they're drinking it, what's in their drinks, how strong the drinks are, if they're eating or not."
