30. “No hablo Ingles.”
I once worked as a door-to-door salesman for a concentrated multi-surface cleaner made from enzymes or somesuch. I get it, people don’t like being bugged at home, but just tell me that and I’ll be on my way with a “Sorry for bugging you at home.” Don’t lie to me.
This one guy one day interrupted my pitch with “No hablo Ingles.” So I backtracked, apologized and began my sales pitch, completely en Espanolish. When he heard a couple of sentences of this, he said, “No thank you, we don’t want any cleaner.” To which I replied, “No hablo Ingles.”
