counter girl 

A girl that only looks good from the waist up. Or in other words a girl whose lower body hides behind the counter.

Dude, that girl that works the checkout is really hot. No nevermind she's just a counter girl.

counter girl 

The sexy girl who works at the counter, gives you free refills, and flirts with everything that comes her way

That counter girl's so awesome, she just gave me a free PBR.
