Quite often when I was a kid growing up in Glasgow, Scotland. That was how people got around. Most people didn't have cars, and taxis were only for trips where you had to get to the railway station with luggage, so if you wanted to get to another part of town, you took the bus. All of them were double-deckers. Only tourist coaches were single-deckers.
Where you rode depended on how far you were going. For a short trip, you'd go "inside" (downstairs). For a long crosstown trip, you'd go upstairs. (Downstairs was called "inside" probably as a holdover from when the upper deck was open. The buses were all fully-enclosed by my time, but the term "inside" was still used.)
Once or twice, I rode on a double-decker tram. The tracks are long gone now, but the trams still ran on Maryhill Road when I was a kid.
