My local is the same.
He's excellent when it comes to road race and TT stuff. He's a former National Road Race champ. But hasn't a clue about stuff for doing long rides. I gave up going there and always buy on line or from sales.
I've had too much rubbish from bike shops and very rarely visit them. But I am pretty fussy about what I use for reliability, value for money and longevity. It's usualy a pain buying fixed wheel stuff too, low quality hubs and sprockets.
Shop: Ooh, these are very good.
Me: No they aint, the flanges are prone to breaking and the bearings don't last much more than 10,000 miles.
Shop: 10,000 miles is a lot.
Me: Not really, not even a years riding, a Goldtech will do 100s of 1000s (wanders off)
