I know for a fact the neighborhood I live in does not tip well if at all. It's not just how I was raised its other factors too. Some people loathe to voluntarily part with their money. I see the reaction of cab drivers, food delivery people, even Chewy.com bc I live on a 5 floor walk up. I've worked since I was 14 or 15, perhaps that's why I tip well, but it has meaning to top more than the average shmoe, but not in a narcissistic way. Nevertheless a lot of people get the short end of the stick with this system.
