Nailed it. I've seen many Payphones that were taken out of service smashed by someone looking for money days after the phone stopped working and before the Telephone company came out to collect it. See the same thing in many locations if the phones haven't been removed. Someone just comes by and smashes the phone to try to get the cash. Then of course there are those who smash the pay phones to get back at Telephone companies.
They could also just get vandalized or hit by a car or something. I wouldn't be surprised to see a lot more than that in damage in a year to one of those things.
