Be a royal for free!
I think the pay is already spot on, I wouldn't ask for any more.
I think you should be proud and very grateful to be a royal marine, being paid for it is an even extra added bonus.
They pay you enough to have a comfortable life and there is so so so much you get massively subsidised or free.
If you were a multi millionaire would you still expect them to pay you? I should hope not *text deleted* you already have everything you need, so surely as long as they provide you with all you need, it doesn't matter how much they pay you.
Surely you want the job for a million more reaons than pay? If you're so worried that ticket wardens get paid more than you, be a *text deleted**text deleted** ticket warden.
You should be honoured to be a royal, and grateful that they pay you.
