I arrived to do the annual fire extinguisher service and maintenance at this location as scheduled. I made sure that none were damaged and they were all in good working order (including checking the hoses, gauges and overall fire extinguisher). I shined the fire extinguisher and put them all back in their places after I tagged them. The customer had gone on an errand so I left my card with reception and let them know I was finished and a bill would arrive sometime in the next couple of days.
