Our hobby shop at Holywell in north Wales stocks a wide range of model kits and almost everything you need for run of the mill modelling and they are very good at sticking to their opening hours. People come there from a fairly long way away.
My favourite though is not a hobby shop at all, but a small engineering supplies company, run by one elderly man ( rumoured to be in his eighties ) in a small industrial unit that opens only on weekdays.
You never go to buy a particular item, you go with a problem and spend as long as you want, explaining it to him. While that is going on all sorts of engineers call in to buy stuff and join in. The problem becomes a plan complete with fag packet drawings and then the necessary materials are brought out. Two bolts and nuts, 2 washers, a cotter pin, a steel rod, brass tubing and whatever else they have dreamt up, all at ridiculously low prices. I was once in the shop for 3 hours and spent £2.90, but you do have to email photos of the finished item to those who helped you.
They call it bodgeneering and they all seem happy to waste half a day on a problem they have not met before, they appreciate the skills needed for model engineering
Sometimes I even get an email from someone asking my advice because they have gone into his shop and he knows I have already had that problem.
I dread the day he packs in.
