After having delivered an eCommerce site to a client, he called me on the phone, explaining that he had experienced some problems ordering products. While on the phone, I explained to him that I would do a test order to see if I could reconstruct the problem he experienced. The ordering went fine, but suddenly he says

Client: “Wow, I got an order from you here. You want that Jacuzzi? I’d suggest [some Jacuzzi name] instead!”

Me: “As I explained to you, that was a test order. I don’t want any Jacuzzi”

Client: “Well, you ordered one, now you have to pay. I’ll just take it of your invoice.”
