How to lose a customer...

My wife bought me a wine refrigerator for my birthday. It's silent, and sits in the dining room and I like it quite a bit. I couldn't find the handle screws that came with it, so I wrote an e-mail to the company asking them to send me screws. Their reply?

From: Customer Support - WEC
"We will send you the screws as a one time courtesy."

So my question is: Is that kind of reply really necessary? Emphasizing the one time. It isn't as if I'm going to hoard screws for the handle of my fridge, and even if I ordered a second set down the road at some point, who cares? Why couldn't they say "Certainly Mr. Pinkus, we'd be happy to send you a set of screws and we apologize for this inconvenience." If they had done that, I'd be super-happy with them, and likely to order additional things from them in the future, but NOW, there is no way I'll order anything from them ever. I'm insulted by their pettiness, which is sad, because we're actually planning on putting another wine-fridge in the bar area, not to mention I liked and was considering some of the other wine-related products they have. Alas....

So Wine Enthusiast, you just lost a customer.
