The Dude Who Brought a Prepared Dish from Whole Foods
Hey, he's not so bad, he probably just had to work late, OKAY?!?!
The Portion Controller
Has a careful eye on the serving trays. Keeps a rigid mental inventory on par with most street bookies. Likely to instigate a Tupperware-redistribution session.
The Person Blissfully Unaware That There's a Finite Number of Chicken Wings
Oh, they just thought they'd take two because they're really hungry but there are only eight of them and, like, 15 people. Either incapable of basic math or just inconsiderate. Probably both.
The Person Who Brought a Salad
Helpful for reinforcing the illusion that you're getting a full plate of food. But, like the dish, this person is really just taking up space without adding substance.
