I know for a fact hotels (or motels) like to scan or copy IDs to be able to effectively bans, because the person working the front desk has no idea who is and isn’t banned, especially if a single hotel company owns or manages multiple hotels. If Hilton/marriott/IHG/choice/wyndham were not almost all franchised, then I bet they would institute global bans. I can’t imagine bars are any different.
