Sadly we have been gringoed on several occasions (about half the time) while riding the buses along the Ecuador Coast. So how do you know if you are paying more than the locals on the buses? Generally speaking you should only pay a dollar per hour of travel time. However along the Ecuador coast we have noticed it is a bit higher at $1.50 per hour of travel time. If the bus attendant thinks you don't know the price he will gouge the gringo for a higher bus fare.
