I'm not saying they need to know everything about a product, but they should know the very basics, particularly manufacturers recommendations.Ducatiboy stu said:No. Not always. Plenty of situations where you buy something from a shop and they dont always know how it should be used
I have walked into plenty of trade supply places ( selling big $$ equipment ) and they always point you towards the manufacturer
I can nearly bet my balls and anyone's balls than if you walked in to buy a $1500 mig welder that the bloke behind the counter has never struck an arc in his life. But he can read the leaflet.
Same as the wholesaler I deal with. The guy behind the counter knows SFA about electricity, can not say how to use the product, but can recite the whole catalog verbatim.
Does the retailer need to know everything about every product..... No they dont.
Homebrew is a specialist interest - if the retailer doesn't know anything about homebrew, they probably shouldn't be selling it - or at the very least, I probably wouldn't be shopping there.
This would be akin to you purchasing your MIG welder from a store that specialises in MIG welding. You would hope that they had some basic product knowledge.
Wholesale is different to retail.
