Went to my local Tesco earlier for a few things, just in time to see some folks collecting their reserved consoles. Was like a military operation, they had extra staff escorting the consoles from the storeroom to the till, then walking the customer out of the store. Got chatting to one of the assistants, who looked a little worried. Someone had posted on Facebook that the store had some consoles and so a crowd was now gathering. Offers had been made to staff and to the folks leaving with consoles, along with a few cross words. I don't remember it being this bad, even in the early days of the Wii.
