Restaurant honor system?

About a week ago I ordered some mac&cheese to go from Noodles & Co for my son. It’s probably on of the cheapest things on their menu. I was nose down in my phone while waiting and when they called my (common) first name I jumped up, grabbed the bag and left. I really didn’t pay attention to it’s weight or anything.
When I got home and gave it to my son he was disappointed to find two other noodle dishes and a fancy salad in the bag with no mac&cheese.
I’m guessing the guy who got my bag caught on faster than I did and got them to remake what I ended up with.

Huh. At the CVS pharmacy, all of the bags are lined up in a rack by last name like that too, but you have to ask someone to retrieve yours for you. Someone should tell them about this other option.

Well now, don’t get me wrong; I appreciate the beauty of it. At some of the other places I’ll occasionally order online first (Potbelly’s and Five Guys, for example), it can be hard to get the attention of an employee if the restaurant is really busy, even if they have a dedicated “line” for online orders. So there’s definitely a plus to not needing to interact with anybody in order to get your food.

I just wonder if there’s a certain amount of anticipated loss that Panera (and others like it, based on Pantastic’s experience) builds into its budget from food theft. Because in my experience, dishonest people come from all socio-economic backgrounds.
