I thought that there was a big warehouse/factory type place, miles and miles away, where substitute teachers went and would just wait; drinking coffee and chatting and such; for a teacher to call this place and say they would be out sick. A substitiute teacher would spring into action and drive seriously fast to school in order to be there before all the kids.
