Structure: scenes

I was in a writing workshop with Tony Craze at the Chelsea Theatre where he suggested only a few basic premises can happen in a successful scene.

X can try and get Y to accept or give up some thing/idea/object.

X can try and seduce/join/partner or separate/break up with Y

X can try and persuade Y to stay or leave a place

X can try and persuade B to take some action or stop (pursuing) some action


The idea is that all good scenes contain these basic wants and if you can't tell what it is, then maybe it's a duff scene. Can anyone think of a good scene that doesn't fit this?
