I can’t think of a delicate way to say what I am about to say. Let me just come out and say it.
The toilet stall is not the place to take a work conference call. I don’t care how important the call may be to you.
If you have to have a bowel movement, you hold it in your office or you face the consequences of your indiscretion in the bathroom.
Do not take work phone calls in the toilet. You specially do not get to be angry at me because I happen to finish my business just as you’re starting to talk. Period.
