Well that is obviously a choice you and your colleagues are perfectly entitled to take. Nobody is forced to go to any open facility if they do not want to. Similarly no one is forced to buy any items they deem non-essential when at a supermarket etc.
The issue is that far too many people seem to think because they do not want to do something which is 100% allowed everyone else should be banned from doing it.
The main bugbear I have is non-essential activities which get in the way of key workers going about their work. This is part of the reason why we had to have the lockdown in the first place, as people weren't doing what they'd been *asked* to do, so they had to be *instructed*. The more non-essential activities take place, the more it obstructs key workers and potentially increases risk to them. As long as people are thoughtful there shouldn't be a problem, but experience shows this hasn't always been happening.
Remember the NHS worker in tears because the shelves had been plundered? We can't have a situation where key workers finish their shift and have to queue for an hour to enter the supermarket simply because people are killing time. Hence there does need to be a realisation that non-essential activities do need to be *minimised*, if not completely eliminated. Some people seem to find the idea of minimising difficult to comprehend!
IMO some people do take the basic services we've become used to like health care, transport, food supply (etc) a little for granted. It really is the case at present that if the key workers lose patience then we might start to find out what it's like not to have these services readily available on tap.
At the same time, *any* non-essential contact is a potential source of transmission, which is what we're seeking to avoid. Again we can't realistically eliminate all contact, but we can try to minimise it.
