I think your experience just shows that guides, like their customers and like waiters, are human and every now and then you get one who's an a$$hole.
So tip them acordingly. It's not rocket science. On my latest trip, the only time the subject of tipping came up was when I asked the outfitter about it. Same with the top-of-the line gear the guide purchased. I was interested in how much it cost.
Maybe if you'd asked the question first your guides wouldnt have felt the need to drop the hints.
