Do you think I said something that pissed him off? Is that why he stopped coming into my shop?

This regular customer used to come in a lot, he was chatty and friendly towards me! And would always talk to me about random things like what he did over the weekend etc. One day he came with his coworker and his coworker order something and asked him if he wanted the same thing and i was trying to be friendly, joke around and i said "hes pretty consistent" in like a lower tone sarcastic voice, he told me he was so i didn't think there was any harm to it. After that he didn't come for a week, and when he did last week he was with his other coworker looked really tense, not like angry or anything just looked at me with a blank expression... he told me he went to starbucks and that his girlfriend took him there, and on Monday when he came in for a meeting he didn't even look straight ahead.. i strongly feel like i did something to piss him off, maybe it was what i said but i really do think he stopped coming in cause i said/did something.. I don't know what do you think
