I just noticed this while watching a stream in Thailand, but this also seems to apply to the West (where I live) and the USA and everywhere because everything is globalized and standardized these days.
Basically, the ceiling/roof is way, way up there, seemingly for no reason. Why don't they put the ceiling much closer to the humans shopping for food? Why must it be so high up? Is this some kind of ventilation thing or something? Doesn't it cost much more to make a building so enormous in height and have to heat up a much larger volume of space?
I don't understand why it's not like a normal room. Then they could put another level on top or just save the money.
