>"...I don’t have enough credentials to become a resident, it was so easy before, get your funds in from the UK, do a bit of cash in hand around the likes of Benidorm and bob was your uncle, but that’s all changed now – hey, don’t be fooled thousands of Brits in some guise or other have been doing the same thing, especially in the entertainment industry!"

Could someone say what this means? I know Benidorm is a resort area popular with Brits but why was cash important if they were legally there anyway pre-Brexit? What's the angle?
