Hard Up

I fell out with the Royal Mint
No cash for me,
No more,
I'm skint,
I'm not a slave to monthly pay
'The best things are free'
As the short of cash say,
I seem to spend hours
Scrabbling around
For any lost treasure,
A penny,
A pound.
Who needs it anyway?
What will it buy?
If these theories fail
I'll give scratchcards a try.
