I really struggled with this prompt. I don't really know any famous movie characters that well that I can use their typical wordings, without which it's hard to write in that character's voice. I was about to give up and go off-prompt, but then I remembered a visit to a coffee shop in the town I live in Wales, where a female police officer popped her head around the door and produced the folowing scene, very reminiscent of Arnie, so I've used that. This scene relates to the female Terminator in movie 3 of the series. I'm afraid I've not done it as a personna poem but hopefully that's ok :)

The Caffeinator

The street surges against my back
until the doors
part
to yield cappuccino.

Tables full of half term kids,
the steam machine
wheezing like and asthmatic air raid siren.

And the policewoman came in,
in search of something,
leaving like the Terminator,
“I'll pop back later,”

leaving the frothing milk
to breathe again.
