A reader wrote to Jen at Cake Wrecks that the bakery at her local supermarket has a new policy prohibiting photography. She heard that it was because the management was afraid the cakes would show up on "that bad cake site." In fact, store employees said it was because their cake designs were copyrighted. That does seem like a logical response; far more logical than hiring professionals or training cake decorators.
Of course this bakery isn't the only chain to ban photos; fact is, most stores now have similar rules. I hear from readers every week who are harassed, shooed away, and even outright kicked out of stores for whipping out their cellphones in the bakery.
Now, far be it from me to criticize rules (even ones I find really, REALLY stupid) but I don't see how harassing your own customers - and ones who often buy your wrecks because Cake Wrecks has made them a world-wide inside joke - is good for business.
Then again, I also thought it would make more sense to train your bakers not to make wrecks instead of trying to prevent people from seeing them, so what do I know?
There are more photographic examples in the post at Cake Wrecks. Link
