If I am at a fast food restaurant then I do not worry as non of it is very good. If I see a sale say a 251 piece set for a grinder and it shows specific attachment s and I get there and it is not the same I get real peeved. After all I wasted money to go there and deserve what they had offered. I often leave with rain checks at lest then the advertised price. After all no one like a guy standing around talking loud enough for other to hear about how they deceived all their customers today.
An american friend told me long ago a price sticker is only the flunkies suggest price and the manager likely can do you better.
My last example of this was a 351 piece set fro 199 ands the 251 piece set was same price. The box was damaged so I had a chat with the manager and took the small set for 100. Nice gift for my brother who has used up most of his tools. It was a socket set.
I don't think anything we buy ever really looks like the picture. Now with advancements in technology they can make anything look twice as big with more color and firmness so a regular burger may actually look like a super deluxe bigger until you actually get it and find out your eyes have been lied to!
Imaging the effects of hunger on the brain's response to food cues
Our brain pays more attention to food when we are hungry than when we are sated. Now a team of scientists has shed light on how the needs of the body affect the way the brain processes visual food cues. In two newly-published studies, the researchers examined - with unprecedented resolution - the brain circuits responsible for the differences in the way the brain responds to visual food cues during hunger versus satiety.

It's all marketing, businesses would bring out close up versions of the real food and make it look like it's a lot bigger and better than it really is. A lot of people would of course take the bait and spend money on something that is a lot smaller than what they expected.
