A lot of women like to get their nails done or get their hair braided and there are shops all over in every city. In my city you can see about 7 or more shops within a 2 mile radius. These shops have a lot of clients and they bring in a lot of money. Most of these shops employ women from other countries and some speak English but some really don't speak it well. African Hair Braiding shops are very popular and you will see a lot of young women braiding hair.
Over about 4 years I have heard raids going on because a lot of these owners are actually pimps and they are taking the tips that you give these ladies and they are making very little to almost no money for their work. They are beaten and forced to work for very long hours. These ladies were brought to the United States Of America and are promised a nice place to live and the opportunity to earn money to support themselves but also to send money back home to their country.
What these ladies didn't expect; they would be sold into slavery and prostitution. Most of these ladies will not report these pimps to the police authorities because they are illegal and they will be sent back to their country. They are also scared that they will be killed. Some of these ladies are living in the back rooms of these nail shops and after dark, they are sold to Johns for sex. They will have to perform or they will be beaten. The shop owner keeps all the money. You will be surprised that there are some women running these brothels.
I have seen with my own eyes, owners taking tip money right out of these girls hands. I don't get my nails done much but when I would go, I would usually get a simple manicure and one time the owner made fun of me because I didn't want to get the more expensive nail manicure and my feet done.
Pay close attention to the ladies when you go to the nail shop or the hair braiding salon because if you see something please report it. You can report it anonymously.
