I had changed into scrubs, booties and hair cover to go into an operating theatre and repair a printer. I didn’t want to have to come out and do all that again if someone had forgotten to charge the electric screwdriver, so I revved it a couple of times while standing in the charge room, which was fully visible from the hallway. A passer-by glanced my way at the noise, did a double take at what might have been a surgeon testing off-the-shelf power tools before starting a procedure, and walked into a trash can. 😁
