There was a Mom & Pop in my old neighbourhood too. Real lino tiles made from linseed oil with a trail worn through to the concrete, tin ceiling tiles and a bell attached to the front door. The guy wore old Carhart overalls with a heavy coat because there was never any heat in the place, and he had reading glasses hung around his neck on a bathtub stopper chain.
He also offered small engine repair and basic machine shop services; had almost any fastener known to man and lots of cool vintage signs advertising long forgotten hardware. I'm pretty sure he didn't consider them cool. The place smelled like 3 in 1 oil.
The place got flattened to make way for the parking lot of the condo development next door. Now its full of Smart cars and $600 strollers
Sad that my kid will never know a place like this because today if something breaks you just a buy whole new one...
