Random story, I was working on a project a few years ago that had a very tight deadline and a lot of code to write. I had been working late in the office most evenings but one night myself and a colleague had stayed later than usual as we got carried away with supporting peripherals​ in the epos.
The cleaner came in on evenings and we had seen her that night, but had not heard anything for a while so when it came time to leave we figured we best lockup the 2 offices.

After making a quick pass through the building we couldn't see her so proceeded to lock up. Fortunately before setting the alarm we spotted her motorbike in the adjacent car park and decided to have another look.

I'm not quite sure why I decided to look in the tiny supply room/closet but fortunately I did as I found the cleaner standing in this tiny room​playing games on her phone 😂
