Last time I ate at BK, the guy taking orders knew only two words of English. “No pro-len” (No problem). And my order was totally different than what I had ordered.
Last time I ate at KFC, I asked for extra gravy - the lady didn’t know what that meant - and gave me more potatoes. I told her I didn’t want more potatoes - I wanted extra gravy. She smiled and gave me some mac and cheese. I said “Gravy. I want more gravy.” (and tried to keep my voice down, but was quickly losing my patience.) She started trying to find an employee who spoke english. I lost it. “Is this the United States of America or MEXICO?! Why doesn’t anybody speak ENGLISH in this establishment?” Everybody stopped and looked at the ‘outsider’ who was losing it.
I left, and never went back.
You’re not the only one that has has this type of experience. I stopped patronizing all fast food restaurants because of things like this.
