DUKWAM? Costco Water!

Water comes out of the tap. It is free, it is right there, and you can stick a filter jug in the fridge if you are fussy. So why does half of Costco descend on the water aisle like the mains have been cut off for good?Jon and Dan get into the pallet-hoarding, trolley-jamming madness of the Costco water run: the crowd you physically cannot get through, the people loading up like they are prepping for a siege, and the bloke who resorted to ramming other people's trolleys to escape.Perfectly normal people. Absolute savages the second there is a stack of bottled water involved.
