Stop in for a cup of coffee

Good morning, coffee's not quite so enjoyable, got a head cold, and here's the frustration I have at the workplace....You come in, the dining room is nice and cool, you get ready to open. Yes if you're a 90 lb woman in a flimsy dress, it feels a little chilly. Please, PLEASE, TRY to understand, once people come in, the room WILL get warmer! When you call down to engineering, they TURN OFF the a/c, and at 7:30 the sweat is running down my face! So then you call engineering again, and by 9:30 it's finally nice and cool again, and as the dining room empties, it gets chilly. This is why I'm sick on my day off.
