Not Behaving In A Presidential Manner

(A customer is ordering her drink. From her accent, I assume she is native English.)

Customer: “Can you tell me where the Cenotaph is, please?”

Me: *gives directions*

Customer: “And is the President there?”

Me: *assuming she means Prime Minister* “No. There’s a ceremony held every Remembrance Sunday. She will be in attendance.”

Customer: “When is that?”

Me: “It’s held every second Sunday in November.”

Customer: “And when is that?”

Me: “Next Sunday.”

Customer: “And you’re sure the President will be there?”

Me: “Yes. The Prime Minister will be there.”

(She gets her drink and walks away.)

Customer: *to her friend* “What the f*** is a Prime Minister?”
