In November I tipped him $20 for the wife and myself.
The couple that were with us tipped him $3. I was pissed at him and when his wife found out she was very pissed as well. (BTW.....he's a lawyer and certainly had more than enough money to tip him well)
In a couple of weeks there will be 10 in our group and I was already planning on tipping him $100 US for our whole group. $10 per person seems about right to me.
