Say you placed an order to go... and then left the restaurant with your food....

lol nice visual! I always feel I HAVE to get out quick!

LOL! One time I was tossing bags at the kids trying to ask them to check and make sure they had their apples and toys and fries and that I got chicken or cheeseburgers for the right kids, and that their drinks were what they ordered.... because I had to move ahead or be run over by this gigantic raised 4x4 truck on speed....

That's a bit of a cynical response. I have only had this happen a handful of times, and one time I regret I just threw out the food because I A. couldn't eat it, and B. didn't have any more time on my lunch break to drive back there, order what I wanted, and eat. If you have a receipt - which most businesses will give you when you pay for your food - and what they gave you does NOT match what your receipt says you paid for, regardless of whether you left and how long it's been when you drive back or call them, as long as MOST or all of the food is still there for you to trade in, I've never had a problem. Never had anybody accuse me of anything, and you can believe people would get mad if restaurant or store employees were accusing them of anything UNLESS someone wanted an order replaced and they ate all of the wrong order. Sometimes they just check to see they did give you the wrong order and they will give you your order and tell you to just keep the wrong order too, since they can't take back any food, they'd just be throwing it away. Another thing, you're right about the regular customer thing. Also if you placed a very large order (and thus spent a lot of money), a place will more than likely credit you, issue you a gift card, or replace the order for free because they want to keep your business, especially now when people aren't going out for food as often. Customer service has deteriorated so badly in today's society, that if I get great service from anybody, from a greeter in Target to someone who takes my order at McDonalds, I am absolutely THRILLED. I would definitely be a repeat customer if I am treated well after they make a mistake. Maybe I am old school, I still EXPECT great service. I go out of my way to appreciate those who actually deliver it.

That's why I asked 'would it depend what was in your bags' lol. If you got something better, ie what you wanted PLUS some, or something you hadn't ordered but that you wanted, I probably wouldn't say anything either.
