Was fitting out a unit in a well known department store once and Mr jobs-worth HnS officer came in and stopped me using a 18" metal hop up until I got a permit, the annoying thing was that in the room next to us there was a load of Poll's (No Helmets No Goggles) bashing out a suspended ceiling using lengths of 3x2 and not a word said to them .
STILL "MUSSENTGRUMBLE"
