There are two feed stores that I regularly go to. One for chaff and one for pellets.
They're both pretty good. Last time I went to my pellets store I wasn't so happy - the usual people weren't there and there was this guy who knew nothing and kept running off to ask someone else. They're normally really friendly and chatty. They were also sold out of my feed.
With my chaff store one person there is really nice and always loads up well before payment etc but if he's not there the other one is not nearly as good and its always kinda awkward.
