You could try to be politic about it. Mention that you are a homebrewer with some experience and let them know that hops should be stored in a fridge. Discuss with them about LME and DME and wheat and barley, etc., etc. If they are interested, you may be able to help them turn into a decent LHBS.
I did this where I used to live. A little convenience store had some hopped LME, bottle caps, and a few kits. I talked to them about getting some grains and hops in. The owner thought it sounded like a good idea. He started getting grains, pellet hops and whole hops, liquid and dry yeasts, some equipment, etc. It was pretty great for a while, but it kinda died out. He said there wasn't enough interest from the customers to keep it going.
Consistency is only a virtue if you're not a screwup
