Why is there a separate fee for the hand sanitizer dispenser?

The separate fee for the hand sanitizer dispenser covers the cost of restocking it and the additional service time, which is why it has a weekly service fee. It is not just a supply cost. A driver does something extra on each service visit. The driver must check the small plastic bottle, refill it with sanitizer fluid, and clean the dispenser's nozzle to prevent clogs. This adds a few minutes per unit to the service route. Companies list it as a separate line item to be transparent about what you are paying for. The zero-dollar charge on your quote is likely the dispenser hardware itself; you are not renting the plastic bottle, you are paying for the labor and fluid to maintain it. For your three-day weekend rental, the service fee is typically charged once, matching the weekly service cycle for the standard units. This pricing structure is common because some job sites provide their own hand cleaning, so the dispenser becomes an optional add-on with its own cost driver.
