We have a back street car wash run by Eastern Europeans, other than the boss, the cleaners change regularly.
A group of African men set up in one of our underground carparks. There were usually two cleaners and one man who watched, then collected the £15 for a full valet. The cleaners were always friendly, with little if any English. The first couple of times I used it, I'd chat and ask which part of Africa they were from but that led to them looking at the boss person over their shoulders. I realised that despite seeming to be an officially approved business in an NCP car park, they were in all likelihood illegal immigrants, or in fact enslaved to whoever had helped them get into the country.
I stopped using the scheme, which disappeared about a month ago. I wonder if the police had anything to do with it shutting down.
It's a real B isn't it, that exploitation like this continues. In reality though, given the war torn countries these men were trying to escape from, hardly surprising.
