Why Do Offices Still Use Disposable Coffee Cups?

Many offices offer free coffee as a courtesy to their customers. The issue here isn't unlike the issues with fast food restaurants. Can clients truly be expected to provide cups of their own? With a lobby, though, there is a very simple solution, though some people won't like it. This coffee is free, after all, so there really is no financial reason to provide coffee anyway, which means clients should be happy to bring their own cups. More than likely, though, people would get offended, even if you did advise them that you were removing disposable cups to cut down on waste.
