Why Do Those Offices That Don't Have Visitors Still Use Disposable Coffee Cups?

Some offices who don't see many, or any visitors, still provide disposable coffee cups. This is not only expensive, but it's also wasteful. Modern offices, especially those where employees have their own desks, can certainly expect employees to have cups of their own and, if the company is feeling generous, they can always hand out coffee cups with a company logo, or something else of interest to their employees. In this case, the cost savings would come quite quickly as disposable coffee cups are never ordered again.
