Now, if I asked I'm sure that Tesco would say fine, but that's not fun, so I'm not going to be asking, just staying. If anyone asks me what I'm doing hanging around the store, then that's it, game over.
I'm guessing that during daylight it's not going to be hard to mingle with the crowds so I'm certain a good 12 hours will be easy, but dull. But what happens as the store empties. Will they spot me? Will they care.
I'm planning to update the world at regular intervals via the magic of twitter so anyone can follow along. Just check for @drhappymac on twitter.
