"Short" is the smallest size Starbuck's offers, but you'll only get this if you ask for it by name. If you do order a "small" the barista
will likely give you a "Tall
" because anyone asking for a "small" will get the "Tall", which is the smallest size for which the prices are actually on the menu. Also only their hot drinks can be served in the "Short" size. Sound confsing? Yeah, I hate Starbuck's too!
