Went to a bar in baltimore last weekend. Bought a bunch of 'premium' drinks (Stella's, Guinness', GG & Cranberry) and received a $0.41 tab. Me and my friends figured it was a mistake or the bartender was gay and didn't argue with it and left a large tip. Last night I was looking through my CC charges and found a $49.15 charge which sounds like I should've been originally charged (including my tip). However I'm a little miffed they would switch the charge on me behind my back and am considering calling them to have it removed (the bartender could've told me he miss charged me as I remained at the place for another 10minutes and they weren't busy). Thoughts?
