The selection is poor (do YOU eat 4 different kinds of lettuce a week?)
The quality isn't great, the broccoli is inedible.
Worst of all, it is run on "the honor system," which means if you don't get there early, you don't get ANYTHING, even though you paid for it. And they act like that's somehow not their responsibility.
How would you like it if your bank ran on an Honor System? "Don't take out more than you put in, or somebody else will lose what they put in..."
In short, it's a RIP OFF!
