... restroom.

For years I worked in an office above a 'hipster electronic device company' (I'll leave the name out of it). They had the entire floor below us and they hired a questionable type of employee to work their support, shipping and return departments. I assume it was due to the number of monster energy drinks being consumed, but they would always overflow into our floors restrooms.

The things I saw happen in those restrooms scarred me for life... When I see somebody brushing their teeth in my office bathrooms all I can think of is "Somebody probably just cleaned out their guages in that sink"
