To tell you the truth, I don't think it's any of their business who is stockpiling food or not if you are paying them good money for it. If there is a large demand for it, then they need to get more to sell. The fact that they can't get more inventory is their problem and if they lose customers, then that's their own fault for not being able to supply the demand.
If it were me, I would drive an hour out of town, when I could, and buy as much feed as you think would stay good the longest. I know it will be hard when the weather changes, but if you can, I would avoid buying from them. They sound unreliable.
As for your friend, I don't think she was thinking very well when she told them you were stockpiling feed. I don't know her, haven't met her, but the way you describe her sounds like she's manipulative.
