Ok, I’m going to the Grand Canyon to go Whitewater rafting down the Colorado river.
We will be taking a tour bus to the rafting destination, then we will go rafting, then we will be taking a helicopter ride out of the canyon and then the bus ride home.
Oh yeah, we will be eating lunch there too.
My question is: What is the proper tip to give to the
1. Bus driver
2. the rafter guide
3. the helicopter pilot
Help, I don’t want to look like a jerk here.
