I used to work in an office with approximately a 50/50 split men / women. In general the atmosphere was always most congenial with wonderful, amusing banter shared by all. Actual examples of this are:-
Me, to a young lass wearing skin tight leggings, "Bloody 'ell, Joanne! How on earth do you get into those leggings?
Joanne, "A couple of Bacardi Breezers would be a good start, luv!"
Me, in the car on the way to work, pulled up alongside one of the more mature ladies, "Get in the car darlin' and I'll show you some puppies!"
Reply, "Aw! Don't I get a shag?"
Me, on being offered a chocolate willie purchased on the office trip to Blackpool, "Gee thanks, Pam! Do they only come in medium?"
Pam, "I think you'll find they don't come at all actually, Mike."
A colleague, as an aside to me, when a young lady had a somewhat overloaded tray of coffee from the machine, "Hey, look at Jacqui, I bet she drops them!"
Jacqui, "No, I don't!"
Everybody was amazingly good humoured and nobody ever thought of "harrassment".
