The only time I've had problems with them was the time (along with Dave) I stood on the grass verge down by the fence - a security guard came over and asked us to move and invited us to use the car park 
That's the only time I've had anyone approach me during my time at Ikea. Any time I spot at Ikea now, I still use that bank beside the fence as personally I prefer the views from there rather than the top floor of Ikea, but I guess either position is good.
Looks like a nice sunny morning! What time will people be heading for? Just after 11 for me.
Did you get down Keith? I might head down on Friday or Saturday morning, despending on weather of course.
