A 70+ year an old man walking past.

A standing outside a motel in a small town saw a 70+ -year- an old man walking past.
She hasn’t had a customer for a while so she whistles at him and says,
“Hey, would you like to have some fun time with me?”
The old man said,
“But I won’t be able to…” “C’mon man…. give it a try… ” She says.
The old man says okay.
They go in.
The moment they get to the bed, the old-timer becomes a machine and makes  to him one hour straight.
When he’s done, the !tute catches her breath.
Exhausted and tired she says,
“But you said you won’t be able to….”
“…pay you.” completed the old man.
