The idea is that you start when there is no emergency in sight, not when its riding at full gallop towards your doorstep. My dad was a farmer, and he taught me that you should always keep a months supply on hand, just in case. Of course, his family keep six months of food on hand, since being snowed in for months was a possibility, but we live in the Cities.Yeah that's all great advice. However this strain of coronavirus was first detected in December on the other side of the world and with no realistic indication that it would become a global pandemic at the time. It's only about three months on from that and only about 8 weeks since it started to look as if it was going to become a global problem rather than a regional one like SARS or MERS. The crazy panic buying started about two weeks ago, so that's about a six week window.
I also have to point out that whether something is 'expensive' or not is entirely dependent on the income level of the individual. It doesn't matter if something only costs 50p if you only have 20p. There are also other practical considerations such as the fact that a 78 year old woman who does her shopping every other day using a hand-pulled trolley literally doesn't have room in it to buy extra stuff, which is the entire reason she does her shopping every other day to begin with.
Regardless, I didn't post looking for pity or sympathy and I'm out of this thread now before I say something I'll regret.
People might have noticed that in the four years I've been a member of this forum I don't post in off-topic. I've just been reminded why.
