Like those 1 or 2 litre multipack bottles?
I've just been to Tesco express (it's tiny) and two separate customers were complaining that there wasn't any big bottles of water about
I thought that was a coincidence, but thinking about it, I keep seeing lots of people in Asda and Aldi doing this too!
I mentioned it to the guy at the till and he said he'd seen an increase for sure, though he wasn't sure why. Last time he saw it was during the first lockdown and they ended up restricting the amount you could buy at once anyway
I know people like bottles water for various reasons, and I have a friend who's DS won't have anything else due to his autism. But surely this is unusual?
