So hurry up and wait (but whats worth waiting for?)

The caption contest is still open for another day so toss in any more two cents you might have before I pick the winner. I don't have time to give you details on the prize, but the words 'jack' and 'shit' figure prominently.
So anyway eating standards in our hall are getting fairly poor and food is being rationed at that. Today for dinner, they tossed some brown goo-like substance on my plate, and I waited for the cook to burst out laughing and say "He he...got you there! Im only kidding!" but she didn't even though I gave it a few seconds. Then the other lady tossed TWO small potatoes onto my plate. I stood there for a few seconds going over my options, before suddenly turning Oliver Twist and asking for more.
"Sorry- cant give you anymore" She said "These are the last we have got" She indicated the tray and shrugged apologetically.
I sat with a few friends who were all picking their way grimly through the meal. One of my friends is absolutely sure the cook hates her.
Well did you do something to piss her off? I asked
"No...she just hates me" She answered "Seriously what's her problem?"
Are you absolutely sure you played no role in making her an enemy?
She thought long and hard and then suddenly remembered an uncomfortable incident. On returning from a long day on campus, she had been confronted with a similar meal and had turned to her friend and said "What the hell is this shit?" within earshot of the cook. The look she got must have burned steel. She agreed that such an unwise course of action must have ended any hopes of a friendly relationship with the cook. In fact, there is a good chance they will now be enemies until her dying day and the cook might even be more than an innocent bystander when she does actually die for that matter.
Well the one thing you don't want to do is piss off the cook. I'm going to keep smiling sweetly and never use Charles Dickens for inspiration again.
