The girl next door
An asset to any coffee shop. Attractive even in her work shirt, genuinely friendly, and an expert at gracefully dodging sexual advances. Exponentially increases the tip-out of anyone working with her.
The tip flirt
Close cousin to the Girl Next Door. Always happy to see you. Laughs at things you say that you didn't realize were jokes, mostly because they weren't. Holds eye contact much longer than you can handle, until suddenly you're tipping two bucks when all you bought was a cookie, and Jesus Christ, you need to leave now, because you just told her you liked her "mouth lips".
