I wonder how many have been returned
No idea. I do know that very many cheap (ie: £5) carwash businesses the length and breadth of the country are run by dodgy characters who employ illegal immigrants at below national minimum wage, often actually on a slave labour basis and that Brits seem quite happy to turn a blind eye to this in order to get a cheap carwash. We are complicit in so many illegal activities in this country when it suits us, and we should really get to grips with criminal gangs who exploit illegal immigrants, asylum seekers etc (in carwashes, brothels, drug distribution or whatever it may be) before worrying too much about a few dinghys full of Syrians arriving at the White Cliffs of Dover. We should also look to ourselves to ensure that we are not complicit in funding these criminal gangs, by ensuring w do not take our business to them. My parents for example who are both hugely pro Brexit and anti immigrant but are also great fans of their local Eastern European dodgy car wash outfit in town at which several "lovely, smiley and polite" Bulgarians valet their car inside and out, top to bottom for half an hour for less than the price of 10 cigarettes. I think my parents are hypocrites of the highest order, but they don't see it that way. No, they see these people as happy, happy, happy in their work, and me as a do goody virtue signaller! LOL.
