I don't care if mine drinks. Or if he has a mint or something. But if he was, say, eating a sandwich or popcorn or cookies, that would bother me in the same way it would if my primary care doctor or hairdresser was eating during their appointment with me--because it would feel like they were distracted and not focused on me. Really, similar to if they were playing with their phone or something like that.

It would be different if my T said something like, "I'm sorry, I didn't have a chance to eat lunch today--would it be OK if I had this energy bar real quick?" or something like that. If it was an occasional thing, and he checked in first (of course, I'd say it was OK). But if we were in the middle of session and he just started randomly snacking or eating a bowl of soup or something, it would bother me. It just seems rude, in a way.

Note that I also never eat anything while in session. I do have some water generally--occasionally tea or coffee. But I see drinking and eating differently.
