Yeah, stopping for a chat with a moron isn’t high on my wish list. Particularly when surrounded by them.I don't know. As you were there you could maybe have asked some of them?
At a guess I would say it would be a mixture of loss of business, some which have permanently closed down after being unfortunate enough to have a business in the most locked down city in the world. Being in a job where you cant "work from home", bit hard working from home as a tradie for eg. Lack of consistency with Government rules, mandates and interventions with a lot not making any sense. Job losses if you don't wish to be vaccinated. Separation from family and friends for a good percentage of a year. Some people with genuine reasons for not wanting to be vaccinated etc etc
Not everyone is a public servant who have not lost 1 dollar during this time or a casual worker who have actually made more sitting at home on job keeper/seeker.
