I was in a massive Tesco this morning, from one end to the other and even upstairs you could hear the vile customers screaming abuse at each other, at checkout staff and at security guards.
Some people needed to be escorted out by police.
Now I'm not going to lie, some shelves were stripped bare, and the choice wasn't amazing but there was plenty of food available, it just wasn't necessarily people first or second choice.
I helped an old fella who was looking a bit befuddled find enough things he would and could eat to make a weeks worth of meals, none of it was the stuff on his list but it was fine.
People really need to get themselves into the mindset that they just need to get on with it and make the best of the situation. No tinned tomatoes, ok well they have tomato paste and stock cubes, make up the stock, add in some paste and some veg and you have a pasta sauce. Not the same as you usually make but still fine.
No loo roll, again not the end of the world, potentially a bit offputting, but chop up a towel, use that and hot wash it.
No san pro, again an old towel chopped up will do and if you have a sewing machine and an old T-shirt, you can make some really nice reuseable pads.
If people can't get past this panic response and start acting more sensibly then yes, an army presence will be the only option, but it's us as a society that will force that decision.
