Here's one post: "I had someone come in and ask me for a mocha frappuccino with no ice. I told him that they are made blended with ice, without the ice you are drinking base, mocha, a splash of milk and some coffee base. He said "the other Starbucks does it all the time" I asked him again if he was positive it wasn't a iced mocha with no ice so I made him his disgusting frapafuckingccino with no ice and he drank it. lolwut? gross."
