Henro, there are many businesses, especially with the advent of the Internet, that are legal, even ethically OK, but not what the customers are expecting. When I bought my carport, I found it on the Internet, placed the order, etc., and of course, I got the carport. But, from the website, I thought I was buying from the manufacturer, or at least from an installer, but I learned that the guy I bought it from simply had the website, got the 10% downpayment in advance, then sent the order to a company in another state, and I paid them the balance when it was installed. So, when I bought a carport for my daughter, I went directly to the company selling and installing them.
It reminds me of an incident in 1969 when I was a detective sergeant in a burglary and theft unit and a woman called and told me she thought a neighbor might be a burglar because she frequently saw him carrying TVs in and out of his house from his van, and that he left a lot of TVs out for the garbage men to pick up. It didn't take too much investigation to learn that the guy had an ad in the TV guide section of the local newspaper for TV repair "in your home". The ad only had a phone number, no address. The guy actually knew nothing about TV "repair"; he just had a cheap tube tester and a supply of tubes in his van, he'd come to your home, check the tubes and if that's all you needed, he sold you a tube and charged for the service call. For anything more than that, he'd tell you the TV would have to go to the shop, and he'd deliver it to a real TV repair place, then pick it up later, and return it to you, after adding a little profit over what he'd paid the TV repair shop, plus the service call charge. So he was making a living and providing a service even though he actually knew nothing about the business.
