Back in highschool, I worked for a local movie theater. One night I was working concessions, when a woman walked up and asked for a “medium Coke.” When I handed it to her, she took a sip, stared and me blankly, and said,”This isn’t a Dr. Pepper!” When I politely reminded her that she had specifically asked for a Coke, she replied,”Well, you never asked me what KIND of Coke I wanted!” I have since learned that in Texas, “Coke” is used as an all-encompassing term for “soda.” Silly me for not knowing.
