I went from looking like a crusty hobo punxor to dressing like a sleak movie star and noticed (in this small town anyways) that I would frequently get discounts on things. Say I bought a pack of batteries a place, they would have some opened ones behind the counter for 50% less, or say I wanted a carton of cigs and they didn't have any left, they'd give me 4 packs with a carton discount, or say I wanted a bottle of jagermiester, instead of buying a more expencive bottle behind the counter they had a chilled bottles (which were cheaper) in the back.
I also happen to be a reasonably attractive white male, I don't know if that has anything to do with it. But yeah, looks have everything to do with how other people treat you.
It;s kind of ironic because when I looked poor people treated me like dirt. When I started dressing up and looked a bit rich (I'm not rich by any means)t I got all these discounts.
