Why is the monthly rate lower than four weekend rates?
I'm looking at quotes for a portable toilet rental for a monthly construction site. The monthly rate for a standard unit is lower than renting the same unit for four separate weekends. I know the weekend rate includes delivery, pickup and one service, but the monthly rental gets weekly service visits. The site has 15 workers, flat ground and the truck can park right next to the unit. What's the business reason the operator charges less per day for a long-term rental? Is it just about the driver's route density or something else?
