If that does not make our decision clearer, let me add a few more reasons that were not explicitly stated. Our menu is now easier to read. Our storage space is very limited and, as a small business, our margins thin: inventory is now much easier to manage and maintain in order. Furthermore, keeping larger cups behind the counter and not using them for espresso drinks would only lead to confusion, misunderstandings, subsequent lengthy clarifications interrupting our otherwise efficient workflow, and would, perhaps, add conflict to our otherwise peaceful coffeehouse. We still offer coffee refills, unlimited quantities of them, even! Sit a while, enjoy what you are drinking.
Also, remember how the coffeehouse used to serve 20 oz hot drinks and people's reaction to eliminating that size drink?
I didn't think you would.
