Small customers do weird things. I had a tiny Saas company and we had approached a local business with a few locations. Our software was in daycare management and would have automated a bunch of their processes. The owner loved the product but didn't want to "rent" our software (ie. pay a monthly fee). She wanted to pay us once and install the software on her computers. Literally if we had said "here's a CD-ROM to install" she would have paid us money. This isn't an example of a customer that might vibe code their solution, but simply to show that customers do weird things and have weird requests.
