This was the UK. I don’t think $4k is “many months salary” for a lot of people in the UK.

I can easily believe someone in such a position would jump (well, politely queue, they are British) at a chance for a "mere" few thousand.
Even at the minimum legal level and without a raft of government hands outs which a person could expect its maybe 6-7 weeks salary.
If we take the average salary then take home per month is pocket change short of $3000
