Sweet and Sour Sauce

So, this woman came into the gas station...

Woman:  I'd like one eggroll and a pack of marlboro lights.

Me:  Okay, would you like sweet and sour sauce with that?

Woman (turns to seven or eight year-old son):  Do you want the sweet or the sour?

(Son stares at mother, utterly confused)

Woman:  Damn it, John, do you want the sweet or the sour?  Pick one or you won't get either!!! 

(At this point, she's actually yelling at the poor kid and I'm watching, completely confused and amused)

Son:  I guess I'll have the sweet.

Woman:  He'll have the sweet.

Me:  Okay, ma'am, here's your sweet and sour sauce.
