"A large Latte please"

More and more we have people over who order a large Cappuccino or large latte or small latte or stuff like that.

And then they see me as an 'unfriendly man' when explaining there are no sizes in these drinks.

Mostly Dutch clients have been brainwashed by big chain coffee company's as Star**** and Coffee Company and do not know anymore that a cappuccino is a cappuccino.
I agree you can make 15cl or 20cl cappuccino's, but I'm against a menu full of small, medium and large sized milk drinks. I'm not even talking about caramel machiato's, 'venti's' and other insane American monster drinks.

I remember Coffee Company arguing a couple years ago that they increased 10% after introducing different sizes in their milk drinks.
Well, mister CC, we increased last year 25% by keep on serving 'traditional' cappuccino's.

Our 'Company Credo' = not more, but better coffee's. The rest will follow.
