well the pizza place can deny service to whoever they want
they're not breaking the law
they are however being starfishs and deserve protest
EDIT: As for the poll: I think businesses should keep the legal right to deny service but if you piss off three thousand people because of it that's your own damn fault
and you probably deserve it
kind of like how it shouldn't be illegal to walk around flipping off everyone
but you're still a loving starfish
