Bar service

Normally this is my tennis evening. Today however I was assigned to do bar service at the club house of our tenniscourt. Ben did this together with me. It wasn't very crowded and pretty soon we decided to put the dishwasher to work because it was pretty full. We wanted it to be ready quick so we used the saving position (spaarstand). After 1,5 hours the dishwasher was still going.
After reading the instruction plate (we didn't see that before) we new why. The saving position is the longest position: 2,45 hours. So closely to the end of our working evening (23.30 hours) the dishwasher finally was ready. At that time this was the result of the evening: the blip shows all coffee and tea-cups etc. that the tennissers used until then. It was a quiet evening.
