A related issue here is that we get streets full of small stores all offering the same basic product. Whereas in western countries we tend to locate businesses in areas with no others doing the same, but with customers who would prefer to buy locally, here the businesses like to cluster together.
So, we have light bulb alley, kitchen equipment avenue, liquor lane (aka whisky street), tobacco terrace, banana boulevard etc. OK, I made up the banana one.
Beats me.
