I bought my wife's bike, which she'd purchased back in England while on a fitness kick, to a local shop in Manhattan for a brake service years ago. I have never forgotten the interaction: the hipster douche who greeted me launched into a multi-minute tirade about how Decathlon was "ruining cycling in Europe" and how I was complicit in doing the same in the USA by bringing this abomination into his store.

I'm pretty sure I know who is more responsible for ruining cycling.

Fortunately my local shop in the suburbs here couldn't be more different. They're patient and lovely with my kids, efficient and non-condescending with my wife, will even send a little car to your house to collect a broken bike for service - whether or not they sold it.
