The operator could demand an exclusivity contract from the landlord, provide faulty equipment, then charge high fees to repair it, eventually leading to many stalls non-functional until the contract is invalidated in court or the two parties settle, the chargers are ripped out, maybe with purposeful permanent damage to the wiring to make it unusable, and another mildly more honest provider comes in and does something slightly better but not by much.

Or, an enterprising landchad could realize they can charge 10% more kWh than people actually pull (blaming efficiency losses), along with a healthy margin for "maintenance".

Lots can go wrong.
