a private’business can ask him to leave but if they have that policy and don’t post it clearly, and actually seat him instead of discussing this with him before they start treating him like a customer, and nothing is wrong, then they should finish tking care of him and mention as he’s’leaving their policy, and make sure they post’on their door they don’t allow it.
it rests on the businessowner to let people walking in, before they come in, and before they start serving them as customers, what - if any - things they ban in their place’of’business. it has to rest with them’because every business is different and it’s the only way you’ll know.
