Yes, the ol' prequalification gambit. I had one here in LA tell me I wasn't the right kind of clientele for his store since I drove to the store in my 2001 Hyundai Sonata. They needed a shovel and wheelbarrow to clean up the dump I took on him before I left.
I was so mad I went to another shop and ordered $18,000 worth of gear, then called the first shop's manager and told him he'd just lost that business. The guy wet his pants over the phone trying to get me to come back.
When I came to my senses the next day, I had to go back to the second store to cancel the order. I gave the guy $200 because I'd been an to take advantage of him.
