But you know, there are other business people that don't care either, orthodontists! Because if there is one thing that they don't get taught in college and high school, it's the nerves system. "Oh, I didn't know it hurts if I pinch your lip against your bracket." or " Oops, your cheek got stuck in between your brackets."
Some toy companies are another good example. My little brother one time just finished a dentist appointment, and kids dentists always give you little toys, but the toy he picked out broke instantly after we left the dentist's office and he wouldn't stop crying until we went back to get a new one. I guess that it was kind of my little brother's fault but still! Making crappy stuff and selling it is just dishonest! So if you want more customers if you had a business, be nice to your customers and don't sell junk!
