I lived in Hawai'i for years and after September 11th, weird things started happening with the mail. My husband's medications, on auto refill with the insurance company, were sometimes sent back. Bills started arriving way overdue. My guess is the "Department of Motherland Security" jobs program is getting a little too big for its' britches.
I would've told them I know what the solution is since I SAW them clean my carpets with it...and if it's not on the list of dangerous substances, to ship it! (although I am not daoubting your assertiveness!)
I love this shop and hope I get it again soon-my carpet is looking a little rough.
