10 things you shouldn't do while waiting for a vacant toilet cubicle
1. Say, "Are you giving birth in there or what?!"
2. Decide the wait is too long and use the sink instead. <-- EEW...
3. Throw tear gas into the cubicle.
4. Ask, "did you drown in there?"
5. Poke your head under the cubicle door, look straight at the person and say with a serious face "aren't you done?...don't make me come in there..."
6. Tell the person he/she is on candid camera and should leave ASAP.
7. Turn on all the water faucets to facilitate matters.
