I worked in a office supplier at one point. People would enter the office, put some documents on the first desk they see and look at the guy sitting there. No hello... No sentence... Nothing... That is usually the point when we knew what was up. The guy would look at the documents and say "you aren't at the right place. Wrong floor. Wrong door. " They would look at us in shock. Sometimes complain that you couldn't tell where you are. It was always the same. They wanted to get something from the government. They had an office in the same building. There were multiple big sign. There was literally 2 signs outside telling you which floor. Obviously our office had a sign too. They passed at least 3 signs in an office building while they were looking where to go... People don't read signs.... They just don't.
