Much like HiaG probably never use to like the unhealthy interest you use to take in his lifestyle, but it never ever stopped you,
Anyhow my point was though, just because someone buys something off ebay or loves going camping in a tent with his mates, does not define them as poor - that would be like judging a book by it's cover, it's a trait that many a poor salesman makes. It's like the difference between if someone walks in in a suit or whether they just rock up in some casual stuff like jeans and a t shirt, it certainly don't tell you their annual income. Unless they are someone that likes to flash the cash, but even then you don't know if they are stealing it or have a credit card that is maxed out.....or maybe even avoiding paying tax, which would add considerably to someones disposable income, I'm not chatting about you, before you jump to conclusions again, other than challenging your definition of identifying someone who is poor. If I walk into a charity shop, it helps two fold, in giving them money to support their cause, and some times you might find an item that is either unique or a fraction of the cost if you bought it new, much like going on a Vinted App, not that I ever have. Personally me, I don't wear watches, I don't wear jewelry, I don't buy apple products, does that make me poor of course not.
