I truly hope people are respectful at businesses now that the vaccine passports are in effect. Getting ID’d at a liquor store, pub, nightclub or cigarette counter has been common for decades. Showing proof of vaccination while we are in a pandemic is hardly any different.
It is unconscionable but not surprising that threats have emerged online toward establishments. Moderators and administrators of online groups and pages have a duty to deter commenters from such nasty behaviour.
Every business can’t have a bouncer at the door to protect employees and patrons from uncivilized guests. Hopefully this is just a lot of hot air and in the end we reach our goal of 90% or more folks vaccinated so that this virus and these issues can start to fade into history.
