So normally when you order food from a fast food chain no matter what the menu looks like the actual food you get looks worse. That is just the way it is.

Recently I got a milk shake as pictured and felt cheated. Why? Normally Denny's gives you the milkshake in a cup and a spare metal container with more milkshake. I think the waiters correctly associate more milkshake with a bigger tip. Thus when a person gives you what is pictured you feel cheated...even though it was just you get getting extra for free in the past.

Here I use the word you as in me :)
