Either works just as badly - as I said. It's always "buff-ay" here unless you're over 80 and posh or putting it on. Buff as in huff, puff, stuff and, um, buff.
I don't think we've had a week without at least a small covering of the white stuff since before Christmas. Most weeks, it has been topped up at least twice, but mostly melts away before the next lot comes. Gah.
