I kinda did this once over 20 years ago. I went to a new place and saw someone I'd never seen before. As we got rolling, we came to a price agreement for a basic massage and HJ. There was no teasing and then when we started the HJ, she gave me three strokes and then told me I was taking too long and she said "times up" and left the room.
I left the massage fee on the table, no tip, and left.
I didn't truly "dine and dash" as I did at least cover the massage price.
As I was walking away, she screamed at me out the window (the place was on the second floor) and I just kept walking. She didn't follow.
