Congratulations to Mr. Best for single-handedly highlighting how entitled and ignorant our designers are of the business model they are working in:
"The challenge , Best said, wasn’t vertical-height bias but merchandising. “It’s actually a stupid packaging/manufacturing limitation. Currently, we have to fit into store shelving, and shelving limits how tall we can go. That’s a real thing.”
Wake up, Mr. Best and realize that the retailer parameters are rules you're not only expected to know, but are expected to work within. Your "designs" are there for only one thing - to turn a profit (not art). If you can't understand that concept, then maybe you should go to business school or watch a couple of Sesame Street episodes.
