And Eupho, I don't understand why you'd be such a dick to the poor girl behind the counter? Especially when you were essentially asking her to do you a favor.
woa woa I wasnt a dick, that was someone else. I paid the girl more than she makes in an hour for about 20 seconds of work.

I guess I worded it poorly, rereading it does sound kind of assholish. I didnt "throw the 20 at her and ask how much she made, $8 an hour?" it was more like

"Do you have a checkbook? I'll give you $20 if you write me a check for $12.49 and save me a trip to the bank."

"Yeah I can do that"

"Sweet, it saves me some time and it makes you like $7.50"

"Heh thats more than I make in an hour"

"Wow, harsh"

"Heres your receipt"

"Thanks, bye"
