(I’m helping an elderly customer look for a book when some guy interrupts, speaking gibberish. I can’t understand what he’s saying at all.)

Me: “I’m sorry, could you try to describe it?”

Gibberish guy: *gibberish*

Me: “Sorry?”

Gibberish guy: *gibberish*

(The elderly customer apparently understands and begins speaking to the guy.)

Elderly customer: *gibberish*

Gibberish guy: *gibberish*

Elderly customer, to me: “Music books?”

Me: “Over there.”

Elderly customer: *gibberish*

Gibberish guy: *gibberish*

Elderly customer, to me: “Where?”

Me: “In the corner.”

Elderly customer: *gibberish*

Gibberish guy: *gibberish*

(The gibberish guy leaves.)

Me: “Uh, thanks for the translation.”

Elderly customer: “Oh, I speak a little of everything.”

Me: “What language were they speaking?”

Elderly customer: “I don’t know.”
