I have a hand car wash operation near me that is staffed entirely by Eastern Europeans. They do full valets as well, with it all being done on a production line basis. You queue up and gradually roll forward through the various stages of wash, all for sensible prices. It is a great service, and they really do clean the car thoroughly.
It is very popular, and if it was closed down due to bureaucracy I think that would be a great shame. The lads all seem to be pleased for the custom, and I reckon, with the tips they get, they do all right, but I also recognise they will never become rich doing this work. But to them it is work, it pays money, and probably gives them a chance to get a foothold to live in the UK, which is what they want away from the conditions they faced in their native lands.
