A fiver's a lot of money to be floating round the average airfield but I should have guessed from the username

..money goes into the treasury to pay for public service wages.

Or, to put it another way, to pay for the public services which the citizens expect to be there ?

(Which require public servants, often on low wages and risking and sometimes losing their physical and mental health and sometimes lives to deliver )

T'was ever thus in public, private and third sectors. On the upside, public sector workers are no longer expected to spend their shifts a thousand feet underground, covered in filth and dying horribly thirty years too early.
