Depending on the place, when you order food as a carryout, you don't always get to see the receipt/charges when being told what the total is. You should always ask to see the receipt/charges even if you order as carryout kind of like when you get the check when eating in however, this example is clearly not the case.

I'd ask to have my credit card charges canceled and told to remove that particular charge or I'd walk out without the food. The credit card surcharge is also pretty ridiculous if you ask me.
