4 people got up on to the roof with a banner, while a magic button was pressed which meant that no fuel pump worked for the whole time. Leaflets were given to passing motorists and local press came down. The garage attendant helpfully taped off both entrance and exit for us while they tried to work out how to get the pumps working again. After 45 minutes 2 police arrived and asked when we would be leaving. We waited til the rush hour died down, the leaflets ran out and they were threatening people on the roof with arrest and we all made a swift exit in time for our evening meeting.
