GOOD tips for new shot girl?!

Hey all! I just started working as a shot girl, and I'm looking for a little advice to help me stand out. I know that you have to flirt, talk, be friendly, dress "appropriately",let the guys think "they have a chance" with you etc, but anyone have any good lines? Good ways to handle their objections when people say no? Cute things to say to help convince guys to buy a shot? As soon as people say "no" I find myself smiling and saying "ok, I'll be back" and walking away, but I'm sure there are ways to put on the pressure a little better! :)I don't want to be pushy, but I know that being aggressive helps. Just looking for anything insightful, to help out! Thanks everyone, I appreciate it! :)
