@streakmachine I visited Ikea about 6 years ago, when my arthritic knee was being a bit sore. The longer I was stuck in that hell-hole the worse the pain became. I soon checked out the escape shortcuts between each section and staggered out of that Black Hole with my knee joint locked as any attempt to walk with it bent threatened me with collapsing.
It took over a fortnight to recover sufficiently to go about life normally.
