A young man had been working as a bag boy in a supermarket for several years.
One day the supermarket got new orange juice machines.
The bag boy was excited and asked the manager if he could work the juice machines.
The manager turned him down.
The bag boy said, "But I've been working here for five years. Why can't I run the juice machines?"
The manager said, "I'm sorry, but baggers can't be juicers."
