I am not dying on any hill. And by all means, eat all the sandwiches you want; I am pretty sure they are delicious. But make no mistake, the behavior we are seeing around these sandwiches, is a fad generated by social media hype.
Sure, because people never behaved this way before while waiting in lines at restaurants, Black Friday, etc. before social media... lol
I witnessed that kind of behavior first hand when I was still dialing up Earthlink, long before Zuckerberg ever stole his idea from the Winklevoss twins. In 1950, someone like you blamed rock and roll for society's ills. Before that, it was letting women vote or those dangs kids with their hoops and push sticks.
People are dumb. You don't need marketing and social media to bring that out in them...
