We often make decisions on certain products or services based on one thing, the brand! It may be that you always purchase an Apple devise, or the opposite you may hate Apple and refuse to have anything of there's, we have the same problem with food and food outlets.
Certain food outlets or restaurants will be on your no go list, not because of a bad experience or from poor reviews but because you think you know what they offer isn't for you, this decision might be one you made 5 years ago but you still stick with it.
This video above shows us just how fickle we can be, take away branding and packaging and the food does the talking. A great marketing video by Greggs and something that does make you think "Am I missing out?"
