Curious, how does a small commercial janitorial business survive for so long? My naive understanding as a non-business-owner is that small entities can survive or even do well if they offer a product that's hard or not worth it for big entities to replicate at scale. Some examples might be art, or a nice feeling of "buying local" from people you know and like, or a niche product whose market is just not big enough for giants to bother with.
A janitorial business doesn't seem to be any of those things. So it seems like an area where a big company would dominate (because, say, a lot of 1000 janitorial carts is way cheaper than a lot of 10). But, no?
