I said that they carry modern slavery risks in our country at the moment. There is plenty of data to support the claim that hand car wash businesses carry this risk; there was recently an initiative to help identify known problem businesses with an app: https://www.bbc.co.uk/news/uk-england-47829016
I recently found out that the ice cream van near us that I have used before is part of a network of vans all around my city that has been linked to modern slavery. It’s not an isolated incident in my part of the country.
I don’t think my statement in regard to the modern slavery risks denigrated the ice cream van industry. If I said ‘don’t use ice cream vans because they are all run by slave masters’ then I would have been tarring the whole industry with the same brush. But I didn’t say that.
