Burger King Coffee

Why... why... WHY...

I've been stopping at Burger King for a large coffee most mornings recently on my way to work. They offer "turbo coffee" - my kind of coffee, it could practically walk away on its own! (anyway... ) So, I go through the drive-thru and order a large black turbo coffee - no cream or sugar packets please. Every day they put the coffee cup in a bag & hand it to me. Why on earth would they do that?! I practically spill the stuff EVERY time I grab it. Plus I immediately take it out of the bag & put it in my cup holder, wad up the bag & throw it on the floorboard. I know I know -- I'm way too anal and think way too much about these things, but it just makes me wonder WHY every single time!
