Nail salon owner is Asian.
Asians, whatever else they may be, are hard-working, industrious, and oddly, expect to be paid for their services. They are willing to take the risks involved in operating a business in a ‘diverse’ neighborhood, but they still expect to be paid. To some of their clientele, this practice of paying for service or food or stuff is considered optional. Thus conflicts arise.
In southern California all nail salons are run by the Vietnamese. Donut shops are all Cambodian.
Many dry cleaners are Korean though I don’t think that industry is dominated as completely as the other two I mentioned.
“The actress Tippi Hedron encouraged South Vietnamese to go into the nail salon business and I believe they still dominate the industry.”
My wife and her friends have had the same 2 Vietnamese ladies doing their nails for over 2 decades.
These gals never advertise and all of their customers are loyal and refer friends and relatives to them.
It may be time for service oriented industries, such as these, to require payment up front prior to services being rendered, in certain neighborhoods. I doubt there is much tipping by these residents, it won’t affect the bottom line.
