Depends on the container. Restaurants love giving me a mouth full of Sprite. A waiter kept refilling my Sprite with water. The first two times I brushed it off; the guy's busy, who cares if he makes a mistake? The third and fourth times just got annoying. Apparently my brother got really angry at this (it wasn't even his drink), so when the guy was collecting the money, he spilled the sprite/water all over the table. I just gave him the 'wtf is wrong with you' look and told him that was a bit too far. on that note, I also hate people who overreact in restaurants. Unless there's blood or a dead baby in your meal, calm the [bleep] down.
