My high school had this problem, and I think it was entirely reasonable to suspend that kid. Kid's dealing prohibited food's in a school should be clamped down upon. In my high school junk food wasn't prohibited, but selling it to students was frowned upon. The school itself didn't sell any junk food or fizzy drinks, but like I said bringing your own wasn't allowed. No-one was suspended, but the more the 'sellers' thought they could get away with the more the sold. There was this one kid who sold Cans of fizzy drinks, ice creams in the summer and even paracetemol. Yeah, he was selling fucking drugs(albeit legal ones) on school grounds.
Allowing kids to sell prohibited foods on school grounds will only encourage them to sell prohibited goods for a career (In my experience, only the 'rebellious' kids who were failing classes seemed to sell stuff and I've heard about one or two of them dealing drugs now).
