I don’t know about you, but I do actually think that this guy has hit on the perfect solution for grabby hands. Joey Tribbiani would be proud. Making a physical barrier between your food and the person who’s trying to steal it is a confident move.
I would have to agree with his annoyance in this case too. Nothing is more frustrating than someone who says “oh, I’ll just have a salad,” and then proceeds to steal all of your fries and half your dessert. Just order proper food in the first place, no one is judging.
