The way I see it, it's not worth your time or effort to "press charges" against her. You don't have your receipt, therefor you have no evidence against her. The sad thing is, this happens ALL. THE. TIME. I've worked plenty of hours in the service industry. Bitches do this shit on a day to day basis. For what? A couple extra bucks? Please.

Call corporate and file a complaint. They will most likely do their best to make it right beyond the $2 that was stolen from you.

But take from this, SAVE YOUR RECEIPTS. If you don't want to save them, TAKE A PICTURE OF THEM. Throw away or delete once it hits your account, but I've seen people steal WAY MORE than just $2... you're lucky the bitch didn't add a 10- before your 6 and make your $46 tab a $146 tab. I've seen it happen.

I've also thought about writing my tip out like you would a check -- like instead of $6, write "SIX" ... no way of changing that shit. :P
