Annelle,
It isn't always busy, so you have to talk sometimes. I doubt if you came
right of school and hit a solid busy bar for the entire shift. Smaller places,
I have noticed require more conversation. All you have to be is pleasant,
accurate, quick, and A GOOD LISTENER. It is much easier to keep customers
talking about themselves, then to have to entertain them. Especially when it's
busy.
After a while of tending bar I'll bet you're not so shy.
Fillup.
