I don't pretend to have the full numbers, but I guess things are more complicated here in Brazil than in the US. A common fuel station here usually have 8 pumps, and usually 4 employees to operate at a time. Due to laws on working hours, etc, there may be 2 or 3 shifts. Without going into peak hours and different # of people per shifts, a standard station may easily have 10-15 employees. Then multiply what you pay to each employee by 2 due to taxes, etc. Not saying it's the highest of the expenses, but employees in Brazil adds up to the operation costs. It's one of the main complaints in business here.
