Oh I had one several years that tried that by trying to load the mower after hours. But didn't even have the proper ramps so it got hung up. I went out and made him unload it. Then want to use my ramps and load it up. I said not until I paid. He tried saying that his Dad had already paid the bill. Well he had to wait until the next when I got cash for the repair and then got told that he was barred from my shop. Not going to put with customers stealing even their own equipment.
