I agree. There are events in one's life that occur infrequently. These include, but are not limited to:
Graduations
Funerals
Births
Emergency Hospitalizations
Bowl game of your favorite team
Dentist
Doctor
Etc.
If you'll look real close you'll probably be able to discern that none of these occur every Friday. These are what your optional days are for.
Management doesn't understand this because they simply get one of their buddies to cover for them while they run these errands and they are back before the drivers get in.
Simply magic.
