If you do this, please stop

For the love of sweet Lincoln's mullet, DO NOT talk on your cell phone while using a public restroom. The people in the other stalls do not want to hear your conversation and I'm sure the person on the other line does not want to here toilets flushing. Your cell phone is now un-sanitary, and you need to spray it with lysol. This also goes for conversations in elevators. Please tell the person to hold while you are in the elevator or take the stairs. It's just awkward for everyone involved.
