Everybody does It Part Deux

You are parched. You walk over to the fridge to get a drink of: juice, milk, soda, etc. After pouring the amount desired you realize...there is only about a swallow or two left in this container...I don't want it. So you put the drink back in the fridge almost as if to taunt the next person that wants that same kind of drink. You don't do it maliciously. You do it because you got in, got what you needed, and got out. You hate when you are on the opposite side of the equation. But as long as you got the amount of drink you wanted, that's all that matters. Everybody does it.
