When I interned abroad in Singapore at a small-time IT firm, the office was in an industrial building that had, uh, less than stellar communal facilities. I at least had the foresight to test the sprayer before use, but I swear it was binary on/off. There wasn't a pressure control knob or anything upstream either.
I eventually got used to blasting myself clean, but I still prefer TP.
