I had a teacher that let me do that. Only one though. I thought it was great, and I really got to know my teacher pretty well that year.In the days of my youth, in school, it was against the rules to eat in class, but during lunch any student can enter the classrooms and eat there in peace.
^ They often used that very same logic for those fresh-off the lunch break, and I've got to say, it did apply more often than not. Considering we had half an hour breaks, I'm hard pressed to imagine what someone could have to do during break not to have enough time to eat something quickly before class. Eh, I'm not really one who ever did much other than eating on breaks, so it's probably easy for me to say. On class, I don't really feel I can say it's inherently disrespectful. What did bother them was someone on the cellphone; if you so much as looked under your desk, they'd stop at the middle of the lecture and tell you to hand it over even if you didn't actually have a phone. I wouldn't be surprised if some people's phones were more often on the drawer than on their pockets.Well, that's why they invented a little thing called a lunch break.
It kind of bothers me when people are eating during lecture. A lot of people in my college love to eat their lunch during class time and use their lunch break to do something else. Why? Because screw logic. That's why.
