The death of "Gentlemanism"

So recently I came across this picture on Facebook and my first thought was "How stupid is this?"

First of all you have to eye it from the non-relationship point.
Because of the emancipation many girls/women are considering this behavior as an assault on their role as a woman. This is caused by feminist movements who were in the beginning of emancipation useful, but seem to bring it to the boil.
Such behavior should be appreciated and not easily dismissed as an act of men to make women look weak. This is why many boys/men stopped such things to avoid conflicts.
By the way last week when I went to school, I was packed to the brink and a boy, who is a class underneath me, opened the door for me :)
Secondly many boys my age stopped such things because many girls took advantage of the boys' generosity and for example let them pay for all of their drinks.
Sometimes I heard of boys who spent 60€ at a party only for drinks.
Sure who can say no to free drinks.
But I think it is the duty of a girl to also offer sometimes to pay.
So you have to let the boys be gentleman and don't shamefully milk them otherwise it is the death of "Gentlemanism" :)
