Context: Filipino and Italian person who looks vaguely Hispanic, living in Southern California, working at a sandwich shop. There is a Mexican corner market directly across our parking lot.
I was sweeping the patio and wiping down tables when a customer (C) asked me (M) a series of questions..
C: "Hey ohhoneyno, what does it say on the mural?" (pointing his sandwich at the Mexican corner shop across the lot)
M: "Oh! I'm sorry, sir, but I don't know. I don't speak Spanish."
C: "Come on.. you know what it says. Just tell me."
M: "Sir, I'm literally the only employee on staff who doesn't speak or understand Spanish. I can ask one of my co-workers.."
C: [getting visibly upset] "No! You know what it says and you're just being difficult! Why won't you tell me!"
M: ".. I have told you.. I really don't know.." [turn to my co-worker with pleading eyes] "What does it mean?"
Co-worker: "It's just the same of the shop.. it isn't really a phrase.. just the name."
C: [overhears my co-worker] "NO, IT MUST MEAN SOMETHING!"
He continued to go on a rant to his family after my co-worker and I walked away.
