Fast food really is Fast

Why is it that the best foods are always the hardest to obtain? It's easy to grab a candy bar or a cheeseburger but if you want some whole grains, it's not like you can expect the healthcare cart to pull up at your office door. How cool would it be to go through a drivethru for a wholegrain wheat turkey sandwich and some milk? Not too many places offer that sort of thing. The reason is that there is next to no market for it. People don't want to eat healthy which puts people like me in the minority. I love junk food but I do my best to limit it because I like feeling healthy and not looking fat a lot more. I just don't understand why more people don't feel that way. It doesn't make a lot of sense to me really.
