(I’ve just finished a transaction with a customer who only spoke Spanish, and am speaking to my coworker who translated for me.)

Me: *to coworker* “I really should learn Spanish. So many customers come in and that’s all they speak.”

Customer: “No, you shouldn’t.”

Me: “It really would help. I have to get someone to translate every time I have a Spanish-speaking customer.”

Customer: “But you aren’t in Mexico! You are in America!”

Me: “Well, sir, America is a melting pot of all kinds of cultures and languages.”

Customer: “But if you come to another country, you should learn the language they invented! George Washington invented English, and that’s what everyone in America should speak!”
