support flush
When you are on the phone so long with tech support that you HAVE to go to the bathroom. It's #2; you can't just leave it there because your housemate will be mad. Even though it's tacky, you just wipe and flush, even though you are well aware that the tech support person can hear the toilet flush.
I was on the phone 3 hours today with tech support, IRS and couldn't hold my poop any longer, so I just did my business and support flushed while he was talking to me.
