Even in our culture where body modification is slowly becoming more accepted, I think there's still a sort of stigma attached to having much more than regular size piercings or barbells and some tattoos.
I make it a point to try and treat everyone equally no matter what they look like though.
Actually, if I had the money to spare I'd probably get my ears pointed (yes...like elf ears) and have a few tattoos myself. =3
I do think the more extreme the body modification, the less chance of finding reliable work without having to cover all the mods up somehow.
I remember one of my mother's friends was forced by managers to cover up a little teardrop shaped tattoo she had near the corner of her eye when she worked as a bank teller, and that was only about five years ago.
