Health and Safety

In the office, a spate of little “health and safety” signs have gone up this week.

My current favourite is the one on all doors to stairwells in this office, which read “Caution : People on Stairs”

I’ve no idea why this could be a risk to health and safety, but what I do know is that whenever I use those stairs, there’s no other bugger on them at all. So shouldn’t it actually be “Caution: People may be on the stairs” ?
