Public transport can't and won't ban you for having a disability that's inconvenient to the driver, won't ban you for being homeless and having an unpleasent odour, and won't ban you because you're an ethnicity that's currently being discriminated against. And in the unlikely case it does, you'll find strong lawful protections against that.
