If milk is rape, does that make this prostitution?
The question:

Is it fair/right for a customer to order what we, at my store, call a "ghetto-latte"?

The "ghetto-latte" is ordering any size Iced Americano, with no water and half ice (This lady's drink is an Iced Venti, no water, half ice, Americano). She then takes the drink and goes to the condiments bar and adds her own half and half.

Seems reasonably simple, right?

Not something you'd expect to cause, say, a three-month, several-hundred comment long flamewar which would eventually get heated enough that comments would be closed?

Apparently, none of us know Starbucks that well.
