Eating out - the difference between a picture and what you get

Megamall in Kuala Lumpur last week. I wasn't really hungry but wanted to take a quick bite, since I am around already. That would mean I could skip diner.

As such, going over to a Hotdog shop called "1901 - A Wholesome American Bite" (actually, they are a Malaysian franchise) and bought one of their products. The sad fact is that while the picture advertising the Hot Dog looked great, the final product wasn't have as good or tasted as delicious as it should. Quite sad.

question: How often is this still the case that companies overpromise in their advertisements? And that the final product is not what it was promised. Can customer loyalty be created with that? I don't believe!
