When it came to my turn just after a couple of minutes, which was not even enough to warm the seat I was in, I was given a choice to either stay there to reformat the laptop myself or to do it at home with a set of instructions on paper.
I was told it would take 1-2 hours, so I chose to do it back home. My brief stay there barely lasted 10 mins and I was out there as fast as a speeding bullet. Alright, I was joking about the last part.
