During my university studies, I was working as a waitress in a hotel bar/restaurant. Most of the time it was a half-time job, but during the summers I was sometimes switching to full time. It was during one of those times when I was working full time that I got the late shift, which was from 4pm to 2am. It was a quiet night, the hotel was almost empty. I expected not to have any customers at the bar, and to be able to study or nap. At midnight my colleague left, and after that I was alone serving at the bar. The hotel night shift receptionist was also supposed to be there, but he was, as usual, napping in the back office.
So basically it was half past midnight, and completely empty and quiet. No customers at the bar. The whole ground floor empty, except for the sleeping receptionist. Maybe 5 rooms occupied in the whole hotel, as he had told me.
And then all of a sudden, a customer appears. He must have come out of one of those 5 occupied rooms. He was 50+ years old, and fat.
