Patterns are hard to establish though, especially with a business that needs run time. The wife and I got “rejected” at a few places when planning our wedding, turns out 3 months (which we figured was plenty) isn’t enough lead time for a lot of that stuff (especially dresses, they apparently want everybody to think they don’t even plant the cotton until you place your order). With these companies probably refusing at least one customer a day due to timing finding the ones you rejected for other reasons gets tough.
You're right. You are using plain old common sense here. But I'm quite sure that the gay mafia will ignore common sense and force a pattern to appear, even if a pattern doesn't actually exist.
Sadly, in cases like these the businesses will start out guilty, and have the difficult job of proving otherwise.
