Paging Ayn Rand...
Remember when private businesses could serve who they wanted, without people trying to ban their ability to say "get the hell out"?
Basically, that's what businesses in England and NYC are doing-- they're using a high-pitched device that's annoying to teens to discriminate for the more mature customer.
Yet, that's "wrong." We have to stop that.
No, don't boycot them. We've got to BAN them.
