Doctorate In Bread Required

(I work at a self-service buffet in a hotel. We have these little signs with the name of every dish except the very obvious ones. I am carrying drinks when a middle-aged guest comes to me and points to the bread aisle.)

Guest: “What is this?”

Me: “Emm… bread, sir.”

Guest: “How do I know this is bread? There is no sign at all.”

Me: “Well, it is obviously bread; it looks like bread, after all.”

Guest: “What if I never saw a piece of bread before? How do I know this is actually bread? You can’t expect us all to know that this is bread. Bring me your manager.”

Me: *fetches the manager*

Manager: “Sir, is there something wrong?”

Guest: “Why is there no sign for bread?”

Manager: “Well, it’s obvious that it’s bread.”

Guest: “This is ridiculous! You think we all have Oxford doctorates here? And you treat us like fools? That’s it! I’ve had enough! I’m filling in a complaint!”

(And he actually did…)
