Help - question about fabrics, stains, and dry cleaning

[tzikeh]

Thanks to some, er, exuberant children at the mall today, part of my pumpkin spice mocha splashed on my very very very favorite coat. The coat is 66% polyester, 32% rayon, and 2% spandex. It says dry-clean only. The coat is red with blue undertones, and the discoloration is small, but definitely there.

I am an idiot when it comes to fabrics. Can anyone suggest anything I can do right now? This did happen over an hour ago, so it's not like I can nip it in the bud, but if anyone knows any tricks, or can warn me ahead of time that the dry cleaners aren't going to be able to get it clean and I should shore myself up emotionally (*sigh*), I'd appreciate info.

ETA: It's not just me who goes to the mall specifically to buy a pair of jeans, and ends up with no jeans but $100 worth of other stuff, right?
