I wouldn't expect anybody in a Starbucks to understand that reference.This sounds cool.
Today in Starbucks when I placed my order I gave my name as Spartacus as a joke . When they called out my order I stood up and yelled “I’m Spartacus!” Everyone looked at me and then an old man stood up from the corner and yelled “NO IM SPARTACUS!” 1 by 1 all the customers stood up and yelled “I’m Spartacus!”
