Vincent Teo(a) They ate food / had food in their classroom.

Note that, although a lot less likely, "They had food in their classroom." could potentially mean "They kept/stored food in their classroom.". Most of the time it's the place that rules out the other possible interpretation. For instance in "She had food in the fridge.", there is no such ambiguity.

Right. But, on the other hand, "They had some food and played some games" is more usual than "They ate some food and played some games." It is the place that causes the problem.
