It's funny, for a large amount of my childhood we had very little money but it's left me with a lot of empathy for those less well off and a lot of gratitude for where I find myself today.
I have empathy for those who are worse off I just don't buy pointless complaining. I grew up in a single parent household (I say household as we were homeless for a while, as back then there was no protection for kids Dad's selling their homes out from under them) with a mother who had two low paying jobs, and we lived like paupers (a saying my Mother used to use). My mother used to have a mini metro but when it was stolen with 3rd party cover the payout was so small she couldn't afford another car, so for the majority of my life we had a zero car household, we grew up in debt, in social housing, living around people who though the world owed them all a favour while taking every penny they could get from the tax paying public.
Yet my mother never complained about other people having more than us, she just said work hard at school keep your head down and eventually it will work out.
So going back right around to the start I don't think anything about the person getting a few quid free charging is an issue, there are far bigger issue to worry about than something that has no material effect on them at all. Society isn't fair, if it was there would be no poor people.
