Familiarity Brews Confusion

(I have been getting coffee at the same place every morning for about a year. I’m friendly with the barista, and he knows what I drink without asking, but we’ve never had any in-depth conversation.)

Barista: “Hey, were you in [Local Bar] last night?”

Me: “No, why?”

Barista: “I thought I saw you and I was calling out to you! Well, I guess I must have scared the crap out of another woman.” *laughs*

Me: “But I’ve never told you my name. What were you calling out?”

Barista: “MEDIUM SOY!”
