OK, so everyone is happy to hold the door open for someone else, regardless of gender.
But who walks on the outside of the footpath when they're with a lady? And if you do, will the lady feel pleased or demeaned?
Clue: I always walk on the outside. And I generally give up my seat for a lady if there's no-where else for her to sit. Plus I always - well nearly always - go to the bar to get the drinks. Isn't that what men do?
