So, vending machine. I'm already there, transacting my soda transaction.
You come up and need something from the fridge. Instead of waiting for me to get my crack-in-a-bottle and move, you open the fridge door while I'm right there.
Now for me to get my soda, I have to bend over sideways to reach the delivery hatch. I fumble the play and drop my soda on the floor, shaking it up nice and thoroughly.
Do you feel even a little responsible? Responsible enough to say, "Oops. Sorry, man."?
I would. He didn't.
I feel like I'm taking crazy pills.
