Jackie (small african American man) set a 4:00 appointment
in stone for that time slot and
Didn't show. He causes a company to lose money in their business by not calling ahead of time to let us know, he won't be able to keep his appointment, so we can fill that slot opening . It only takes a few seconds to call out of respect.
A trip to the bathroom is a necessary function of every person,  using that time as an excuse to call is intelligence.
Business would be a different point of view if he was sent home from work without a reason and not paid for that day.
