I was at the Pita Market (restaurant) in the local mall and the guy charged my debit card 5 times.?

I purchased a gyro, iced tea, and fries for $11.81. The numb-nuts could barely speak English and didn't know what "Visa Accepted" meant on his standalone credit/debit device. He started frantically sliding my card repeatedly. He did this in a concealed manner under the desk and was looking at my card a lot in a suspicious way. I suspect that he may have copied down all my information which I am very concerned about. So anyways, the f**kingidiot and I got into a long argument and he couldn't give me a receipt. Then, out of nowhere, some guy that works at Radioshack came out of nowhere and started speaking in Spanish with the Pita Market guy. Radioshack guy started messing with the machine and my card. He then told me I could go. I refused and said I needed a receipt. He went back to trying to do whatever it was that he thought he should be typing into the machine. I got my high school checking account card back, and after a while he said to just come back later and find him and he'll give me all the money that was overcharged back. I argued that the Pita Market guy would probably say he doesn't know me. The Radio Shack guy ured me they would and if they didn't to find him. So when I got home, I looked on my account balance online and it showed that the c0cksuck3r charged me five times! That's $59.05 on one single meal, a meal that should have cost $11.81. What should I do? I plan to go to Chase tomorrow and explaining the problem, but after all the trouble I went through, I want my meal to be complimentary. After all this, when I finally got to sit down to eat it, my once hot meal had turned cold and the fries were soggy and gross. All because of ignorance. What should I do???
