One visit can make or break your opinion and willingness to return. In this instance, you know what really chaps my ass? A rude bartender. I realize you probably don't make great money, what with the cheerleading conference in town, but a smile and a quick check-in goes a long way. Our ice queen bartender had about 3 other people at the bar and still managed to make me feel like a dorky braces-clad middle schooler at the school dance (let me elaborate - I was a huge loser that only cared about getting straight A's and no one would ever ask me to dance- a girl with a giant cleft lip got asked to dance though). A little goes a long way. If you are in the service industry your tips come from your attentiveness and happy demeanor. Absolutely do not charge me $15 per wine with that sass either. No ma'am.
