When clients arrive at my door these days, they often arrive with a coffee in hand. Coffee and tea used to be served in cups, now the container looks more like a small bucket than a cup. Apparently from a sales perspective it is more lucrative to sell tea or coffee by the bucket than it is to sell it in small cups.
In fact, it is very much in the interests of the seller that customers consume large amounts of coffee and tea. After all, increased consumption means higher profits. The question is: "Are you drinking more coffee because you really want to or because someone else wants you to?"
