The Dominator or Stupid Earls

In keeping with tradition, I dominated Andrew and Ryan and video game sports last night. First giving them a schelacking in NHL 2k5 and then following up with a last minute victory in NFL 2K5. Needless to say, Ryan was not impressed.
Prior to that we went to Earls for a drink. I had a chicken sandwich and white russians... tasty. I agreed to pay for Andrew's meal, as I owe him some money from the Bomber game. Using my credit card, I told the girl that I would be paying for the two of us. When the bill got back to me, I signed it and added a tip. Then, during the middle of the night, I woke up realizing that she had overcharged me! She had given me a billl for the whole table! (Ryan and Tina only had one drink a piece) I paid about 10$ too much! Not wanting to assume that she did it on purpose, I can only gather that it was an accident... The only problem is whether or not I can get the bill fixed at this point... With money soon to be a tad tight, I can't afford to go handing out 20$ tips to attractive waitresses... I guess I'll give Earls a call to see if anything can be done... What worries me is that Ryan paid cash for him and Tina so there is seemingly no record that I have that he paid (other than my word). It's possible that the Earls girl just pocketed the money... That will make it my word against hers. Not knowing how Earls handles this sort of thing leaves me thinking that I might be out 10$... Oh well, you never know unless you try!
