“The matter cannot wait until to-morrow. What if you were to replace this wheel instead of repairing it?”

“How so?”

“You are a wheelwright?”

“Certainly, sir.”

“Have you not a wheel that you can sell me? Then I could start again at once.”

“A spare wheel?”

“Yes.”

“I have no wheel on hand that would fit your cabriolet. Two wheels make a pair. Two wheels cannot be put together hap-hazard.”

“In that case, sell me a pair of wheels.”

“Not all wheels fit all axles, sir.”
