Odd coffee notation on menus On a trip to Texas I've noticed that espresso drinks are listed on menu boards as "3 oz.," "6 oz.," and "8 oz.," instead of "cortado," "cappuccino," and "latte," respectively. I have not seen this notation anywhere else. Is it unique to Texas, or a new convention that is still catching on, or what?
i'm wondering if this is a wee joke?
In any coffee joint in north america it's common to have a name for the size of a drink like vente, grande or small medim large, BUT these are also associated with eactly these kinds of OZ sizes 

For example on the startbucks coffee sizes page, it reads

The drink sizes we currently offer are:


Short [8 fl. oz.]
Tall [12 fl. oz.]
Grande [16 fl. oz.]
Venti® Hot [20 fl. oz.]
Venti® Cold [24 fl. oz.]


also, i may be reading you incorrectly but
"cortado," "cappuccino," and "latte,"
are types of drinks;
oz on the other hand are sizes.

you can have any size applied to a latte for example. 

???
apologies if i have misinterpretted you.
