My idea is to have drive through (the cart style) protein hubs. Each cart will have a wide menu with the options of different protein shakes for different purposes. Consumers can choose which level they want (meal replacement/weight loss, lean muscle, muscle building, maintain gains, etc). They can also request the level of their protein -think top shelf liquor but in protein form, their mix-ins, and if they want it blended with ice. This allows for total customization and satisfaction. This will serve a variety of people, not just the gym based group. Being a powerlifter, this is something I wish they would have everywhere. It can also be sponsored by companies trying to put out new products, and workers will be knowledgeable about each protein.
