You are pretty insecure OP. It's not all about you. There were probably a lot of customers and they really did need more cashiers. But no, you decided that it meant something about you because everything does, right? Get a grip. YDI

Or she opened another line because it's her job?

If she treats people that poorly..move on.

You may consider her your crush...but it sounds like she considers you her stalker!

Well, what were you buying?

Did you have a lot of food?

theres plenty of cashiers in the sea, and after She's dumped you, she will be sleeping with the fishes soon too... No but seriously there are plenty of other girls out there... sleeping with the fish.

maybe her shift simply ended? iv been clocking out and had people try to order, so i've had to yell for someone to come and serve. im sure they didnt take it personally

Maybe it was the end of her shift? Maybe there was too many people in the line? Maybe she needed to go on a break? Did you ever consider this?

That's her lose OP. Sorry. Slide on over to the next cashier. And walk out with your head up! Too many people in this world to worry about her.
