Bartering

"Have you any horses for sale?"
"Sorry we're pretty short on horses at the moment"
"I can pay for it"
"You can't get one for love nor money"
"You could have my kingdom, though it won't be worth too much after Brexit"
"The line's breaking up, What did you say?"
"I said a horse, a horse, my kingdom for a horse"

Spotted on Henley Street today.
