I've just been reading about the rise in hospital acquired Covid infections. Staff are complaining that they're required to return to work after infection and/or self-isolation without being tested. Presumably, hospitals are short-staffed. In those circumstances, it's not surprising that elective surgery is being postponed.
The hospital where I had my diabetic eye test is a day hospital, so doesn't have Covid patients.
The only solution is to get community transmission down, which is why I'm not fed up of following rules and, like you MayBee, go even further.
My personal opinion is that the government doesn't have a coherent plan and has wasted billions on the aborted Test and Trace scheme, bogus PPE contracts and the current asymptomatic testing, but that doesn't mean that I'm going to stick two fingers up (metaphorically) at the "rules".
