At the grocery store.

I was getting some eggs and a woman comes into the aisle.
Woman to clerk: Do you have Diabetic Food?
Clerk: I guess stuff without sugar would be good.

I'm in the coffee aisle.
Same woman: Hi how are you?
Me: I'm fine thank you.
Woman: (pulling a card out of her wallet) I lost thirty pounds and now I work with people.
Me: OK. Well don't assume you and I have anything in common.
Woman: Oh. Well. What are you doing?
Me: I'm shopping.
Woman: (shoving the card back into her wallet.) Oh never mind.

Even if I were looking for someone to "work with" I think I'd prefer them to know that food doesn't get Diabetes.
