You dropped your purse !

I saw a woman drop her purse in the street this morning, so I quickly followed her.
As I was just about to tap her on the shoulder she started running for a bus.
So I ran after her shouting, "You dropped your purse! You dropped your purse!"
She didn't hear me and proceeded to get onto the bus, so I got on the bus too.
As I walked to the back of the bus I breathlessly said,
"You dropped your purse on the street outside McDonald's."...
"Thank you so much" she said, "Where is it?"
I said, "I just told you, on the floor outside McDonald's."
