Discretionary spending is one of the first casualties of tougher times, so we expected a drop in responses to our latest survey on interior shops. When you need a new engine, you pony up. But the airplane still flies with threadbare seats and cracked vinyl. You can tough it out.

But this mineshaft canary survey surprised us. In 2008, we got 209 responses—not an overwhelming number, but enough to see some trends and make some solid recommendations. This time we got 132 responses. That’s a 37-percent drop, which is much more significant than we’ve seen on other surveys past to present.
