ON THE VENTI FRONT . . . From one who knows:

Venti is a coffee size at Starbucks – the largest size you can get. Rather than small, medium and large, S-bucks offers something like tall, grande, venti. They want to make it all seem bigger and more mysterious. I try to stick it to the man sometimes by just ordering it the basic way, "Small coffee, please." Sometimes they don't know what I'm talking about.
