But having to turn away a group of people at the door was an unavoidable matter. Perhaps people didn't feel it now, but soon, there would be a very noticeable change.
Smartphones were naturally becoming more intelligent. In the future, wallets could be directly omitted, and eventually, even transit cards would be unnecessary. Even further, in time, there would be no need to carry keys when going out, as everything would switch to fingerprints or passwords. So, later on, a single smartphone would be entirely sufficient.
And even if some people were stubborn and insisted on their old ways, when the need for health codes arose, they would have to switch to smart phones. That stubbornness would be useless unless they chose not to go out.
So, it's best to keep up with the times to avoid being left behind.
