I honestly think a lot of this is about people feeling some kind of inverted snobbery about others having second homes. But as someone else has pointed out on this thread, a second home doesn't necessarily mean that someone is an upper class twit MP type. There are lots of circumstances that lead to this - tied houses with jobs, military, needing to live in a location for work and frequently visit elderly parents in another location - etc.
I think it's people stopping at petrol stations, where there are other people, going in to pay, wandering around to get milk and M&Ms etc.
I don't do any of that so you can sleep easy. Pay at pump, gel before and after.
Anyway, none of this is about whether someone travelling to a second home will cause more Covid, it's about the fact those are the rules and you're intending to break them.
But it should be about what will cause more Covid. Isn't Covid the problem that we're trying to solve here? Why are you mad at an action that doesn't spread Covid but not mad at all the people who 'ate out to help out' (I didn't) just because those actions were inside some set of rules that a blatantly corrupt government has set out?
