My wife was at the supermarket, unrelated to this. She was in before the announcement and she said within 15 minutes security guards were having to pretty much block the door way in. She said the number one thing people were buying was loo paper.
She said it was full on panic stations.. People never learn...
Exactly same thing happened to me. Carpark maybe 20% full when I arrived, when I left chocka and double parking rampant (I was there 20mins max). Toilet paper and chips (crisps) seemed the big goto item.
I had toilet paper and for some reason felt stupid going through checkout. It was on my list!
