You tip your VIP Tour Plaid $800? I can tell you we don't come anywhere near that. There are three of us. We tip them, but definitely not 20%. The number of people in the tour is a factor for the amount of the tip as far as I'm concerned. If there are 10 people, then likely a tip could be more. It would have to be a stellar Plaid who goes above and beyond. In fact, some guides have been very lacklustre to say the least, compared to others. A tip should never be "expected" at any rate.
