I had an appointment to donate blood recently. The computer system at the blood bank kept crashing. The staff had to reboot it a handful of times causing everyone’s appointments to be delayed. Some folks expressed their displeasure and were chirping about waiting to donate. The quick thinking manager opened the supply closet and broke out these bottle openers and distributed them to everyone waiting. The distraction worked – people calmed down while the staff (and tech support) got the computer system fixed and the blood flowing.
