And I'm not saying this lady did this, but I once worked with a guy that would literally stay in the bathroom for a total of like 90 minutes a day. I knew him well, and he was a good guy, but I think he got burned out.
Like 5 times a day he would "go to the bathroom." Which would entail him slowly walking to the bathroom, stopping for a few minutes to talk to someone, disappearing into the bathroom for 10-15 minutes and then slowly walking back, stopping to talk to someone along the way. So, the process of "going to the bathroom" was this 20-25 minute process.
