In our office, it's not an issue that people don't wash their cups out, because our building has a cleaning crew and they wash the cups for us. Why is that so difficult?
If you operate a coffee shop and don't want your customers to give you dirty coffee cups, make it easier for your customers to give you clean cups. That means having some kind of customer-facing sink or washing station towards which a sign directs customers to wash their mugs, regardless of whether they are already clean since we all know different people have different standards for cleanliness.
If you have co-workers who ride their bikes to work, we don't hem and haw over how smelly bike riders are going to be on hot summer days and how there's gotta be some alternative to them riding their bikes. Instead, we install on-premises showers. Bike riders are happy to take showers when they arrive. The showers are kept clean by the facility's cleaning crew. Everybody's happy. Why is this so complicated?
