I was fortunate enough to have good compassionate bosses.

So we had to stand at the registers, but they let me take an early lunch and use a chair the one time I almost fainted from low blood sugar, or on another occasion prefaced "You cant sit here" with "I know you don't feel well, but..."

They were also fairly good with communication, and problem solving, and delegating tasks by a person's skills.

So anyone who hung around for awhile was pretty loyal.
