I was in a store yesterday and they had a display of various bacon themed products: bacon action figures, bacon fridge magnets, bacon mints, bacon band-aids, bacon dental floss, bacon soap, bacon kool-aid - you know the usual stuff (and, no, I didn’t make any of these up).
Not too surprising - I knew bacon was “in”. But alongside the bacon display was another themed display. And it was all pickle products. There were just as many pickle-themed products as there were bacon-themed products.
Unless I’ve missed something, no, it’s not. I’d say that you’ve found a single store that’s an aberration and/or trying to start a pickle craze where none exists.
