How sexist is this?

As I drove into the car park of Westone Manor Hotel tonight there were a few places left to park. I sat in my car and just giggled at the sign. I then had a quick look round the car park to see if there was another set of places that said "men only" ... Nope!!!

How funny is that?

There was another sign that said "DEAD SLOW" not sure why that is funny? Perhaps my warp sense of humour.
