You and I could get along just fine, Queen. I, too, must keep my gurgling stomach at bay and scarf down what I can before and between classes or during breaks. As the instructor, I'm supposed to set an example.
Not that they all follow it, of course. Too many students think that the classroom is their personal entertainment center and dining room. Never mind the noise, never mind the mess they make, never mind that the college honchos have handed me a policy which flat-out states that eating in class is a disruptive behavior. Never mind that the custodians get stuck with more dirty work than they already have. Never mind that we get bees, wasps and the occasional rat.
Never mind any of that, because nobody/nothing seems to matter to the crunchy munchy contingent except their own immediate gratification.
