I finally did it - I returned a dessert item because it was absurdly tiny. Here you might envision a slice of a cake-type item the size of an acorn. This was something I got to go-checked when we got to the car, because another time there had been an error. I was so incensed that I went back and very sweetly suggested that a mistake had been made in slicing said cake-type item.
The manager (or owner?) was very nice, but said that the item was pre-sliced and that that WAS the portion size. So, I asked for my money back.
I have to say, this was by no means the first time I found an amount of food served to be almost an insult to my intelligence - and I'm not one to require a huge amount of food to be happy - but it was the first time I was able to do the deed. I'm sure I heard the Rocky Theme playing in the background.
This is not a monetary issue in my mind, although I can see that if you're spending a bunch of money on a food item, you might be even more annoyed by a thimble-size amount.
Have you had this experience? Did you send it back?
