The Supermarket Queue

Jeff is standing in the supermarket queue, when a woman with a crate of beer and crisps cuts in front of him.

"Excuse me, Could you go to the back of the line?" Jeff asks.

"I've only got a couple of things".

"That's not the point though is it?"

"Can't you just be a gentleman?"

"Look its not about that, I've been standing for ages, you can't just cut in"

"What happened to ladies first?" She asks struggling with the beer.

"Would you like me to help?"

"How dare you!?"

"What!?"

"Women are just as strong as men you know!"
