I was a trainee programmer in a small software house in London (30yrs back). 10 Staff all run of a little Unix box that was located on a table to the right just as you walked into the office.
As I was keen I was often the 1st one in and would flick the switch on the machine to boot it. This process became one of nonchalance until 1 day I did it and then walked passed the MDs office to see a bunch of faces looking out of the window inquiring why the demo had been so rudely interrupted.
