When a place is owned and staffed by locals, it often operates at the 'local speed'. I've been in Tim's in small towns where a lot of the customers are locals. They're ok with the speed and often take the opportunity for a little catch-up. It's not just Tim's. Go into a Robin's Donuts in Atlantic Canada, particularly NL.
Indeed. It doesn't seem as prevalent now but for a while, a lot of small town Tim's and fast food joints relied heavily on seniors (I always thought it was sad that they had to take these minimum wage, on-your-feet jobs), and challenges with the tech and hearing in a noisy environment were regular issues.
