The two main bathrooms have clocks over the door so they can be seen from the entire bathroom, including the shower. No way I'm taking my phone into the shower! Powder room does not have a clock.
For decades (25 years) I worked overnight shift, up at 5 pm, so I had over 5 hours to get ready. When I moved to a more normal shift, I was up at 2 am, ate breakfast, shaved, brushed my teeth and out the door by 2:40 am to be at my desk at work at 3 am, so I had to keep an eye on the time. 14 of the last 16 weeks I worked remotely from home. Up at 2:50 am, logged in and ready to work at 3 am. I didn't get cleaned up until my lunch break.
