I hate when servers steal money.. I gave my server...

I hate when servers steal money.. I gave my server $20 for a $13.47 tab.. and she brought back $6.. so she stole 53 cents from me.. now some might think this is petty.. but if you went to the restaurant and the check was $13.47 and you left $13... do you think the management would come after you? So.. we agree this is theft and it should not be condoned.. I will go back soon and explain the situation.. but I hate that this has to be explained.. the stupid thing is that LJ.. would have gotten a $3 tip.. if she hadn't stole my money..
