(assuming you meant PAYD)What’s do special about PAYS?
Is it because there is still the belief that soldiers cannot manage the basics of life?
They can be handed a rifle and ammunition to go on the range but can’t be trusted to manage their money.
Arrangements are in place to ensure soldiers can eat all month long.
Supposedly they are too proud to use the process but aren’t too proud to borrow off their mates.
There will be soldiers who need the life lesson of discovering that their money needs to last a month, and there is the official process plus the favours of others until it becomes a regular occurrence.
The other possibility is that they buy everything on credit ending up committing their money to repayments. But there’s a whole organisation full or welfare to give all the help they need.
