I used to own an ice cream shop, and we had vegan ice cream, and a pretty good following for it. I got so I could recognize them as they were walking from their car.

One quiet day, I saw this older couple start getting out of their car, and I said to my assistant "They're vegan." She asked how I knew, and I said "Just look at them, they're obviously vegan." She said "But they're so old." "You'll see," I said.

They walked in, and the first thing the old guy said was "We hear you have vegan ice cream, we're vegans!" and I could sense my assistant's head swivel to look at me in my peripheral vision.

As I made his ice cream, he went on to tell me how his wife makes vegan steaks so good, I wouldn't be able to tell the difference. Yes, I could.
