Re: Mind your head
I’m 6’2”, so tall, but not a giant.
I was in a shop many years ago when I bent down to avoid the clearly labelled (with yellow and back stripes - the full works) low head hight ceiling transition where presumably they’d knocked through to extend the shop floor.
In doing so I missed the equally well signed trip warning on the floor transition.
I also once walked into a full height mirror in B&Q which happened to be angled reflecting the shower parts in the adjacent isle I was desperately looking for...
