I have that issue, I can't say Venti, but I can say large. One time I said may I have a Large coffee, the Starbucks employee said "did you mean Venti". So I thought I would fuck with him, so I just yelled out THANK YOU GOOGLE FOR CORRECTING ME. Never had a problem at that Starbucks since. Now I just go in, and not say nothing I just point to the board, and watch them guess what i want like it's a game of family feud.... I get the family thing my dad use to tell at me and tell me to hurry up and get it out. He didn't have all day. It's really fucking annoying
