My accountant manages the books for a gas station. A couple of years ago the IRS was auditing the gas station and put the screws to them because the gas station had a phone booth. The IRS wanted to know how much he made off of it either in change or lease payments. They wouldn't believe him when he said it was empty....as in NO phone. The phone was removed years ago but they had to drive the agent to the station and prove that there was no phone.
The places that do have a pay phone are generally places I'd never stop to use it.
