Query: unknown hose fittings

I purchased this waterfall faucet, and have been to 3 plumbing supply stores, none of which have fittings that allow this faucet to be attached to normal plumbing. My valve openings in the bathroom are for 3/8in female hose ends, but the faucet comes with a size that no one can even rig with multiple adapters. It's got a compression fitting, but not with compression threading! The threading is for normal piping. Therefore a seal can't be made between the faucet hose fitting and anything else. Very frustrating, so now I'll have the added hassle of the return.
