Got Goldfishes

Actual event from work the other night:
Woman comes and orders a fish sandwich.  We make it and give it to her.
Not five minutes later she is back at the counter.  Her purpose?  Return the uneaten fish sandwich for a roast beef sandwich.  Her reason?
"I can't eat this 'cause I ain't got no teeth!"
The woman is in her late twenties or early thirties.
So, she gets the sandwich she wants and as she is turning around to go sit down, the guy she is with comes up and starts yelling at her.
"YOU REALLY NEED TO GO BUY SOME TEETH WOMAN!"
My god, what a wonderful area I work in.
