I could get behind the rules that made sense such as washing your hands regularly, using hand sanitiser on your way in and out of shops etc. But I always got annoyed by the rules that just made no sense.
In between lockdowns, when holiday parks were open, we went to a caravan site and went in the restaurant for food. I went to the bar area to order. There were arrows on the floor to follow and to get there following the arrows it was about triple the distance than to just walk up to the bar without following the arrows. Yes, I could understand in busy periods these arrows stopped everyone being too close. But on this day there was no one else there. So I didn't follow the arrows. And the guy at the till told me off for it. As if I'd just spread Covid all over the restaurant for going the quickest way to the bar in a deserted restaurant.
And mask wearing on buses. You had to wear a mask unless you were exempt. Children under 5 were exempt. People with certain conditions were exempt. The driver was exempt. So you could be on the bus with your mask on but could be surrounded by exempt people with no masks anyway. One day I was rushing to get my 3 year old to nursery and forgot my mask. Driver told me off. I said I could be exempt for all he knew. He argued I had to carry an exemption card. I argued that I was from the same house as my 3 year old who didn't have to wear a mask anyway so if I was harbouring any germs then so was she. He also wasn't wearing a mask. I said I was sorry, we were late and I needed to get her to school. And then went and sat down. He told me off again as we got off. My parting shot was that he might want to open the windows on his bus as surely keeping the air circulating would be more beneficial than insisting on everyone (except him) wearing a mask.
And like someone else said, bubbles in schools. Year groups being kept away from each other but siblings in those year groups obviously mixing at home. To me it seemed totally pointless to try to keep the children separated when the different sibling groups would ensure the mixing of any germs anyway.
And it has annoyed me for years now that pre Covid our local swimming pool was open all day every day and you could get into the pool at any time and swim for as long as you wanted. Covid shut it down for about two years and when it did open it did so with very limited times for swimming and each session only lasts for 50 minutes. So my kids who used to spend a lot of time in that pool now very rarely go because of the very limited times it's available for them.
