I used WAIA last year in the supermarket, right around this time.
You see, I'm overweight. And I had a shopping cart full of snack cakes--Little Debbies, Tastykakes, Entemenn's, Drakes--and snack food like cans of Pringles and the like.
A guy stopped me and commented that I really shouldn't be eating that type of food and that I needed to loose weight.
Well, yeah, gee, I know that.
However, all the food in my cart was for a care package for my brother in Afghanistan. That's what he wanted for Christmas.
I replied, "What an interesting assumption!" and watched as his expression grew very puzzled. It clearly wasn't the reaction he was expecting. Then I went on my merry way.
The nerve of some people.
