It was like, making fun of the customers, but not really intending to.
Bob is the regular... he goes to Starbucks every day, multiple times a day... you all know and love Bob. An annoying, creepy fat dude with a bearista fetish, who's traveled all over the world collecting mugs, has a penchant for lame jokes at the register "I don't need the receipt... you can keep it as a souvenir! LOLOLOL!!!" The employees all give a forced, awkward laugh. And he's got an overmodified drink, of course.
Not Bob is just going into Starbucks for the first time... another annoying fat guy, trying to be funny, "I'll just go in there... yeah, and be like, 'Can get a tall... grande latte mocha... with a twist of lime!'" He goes in, gets confused, grabs the wrong drink... epic fail.
All of this interspersed with a really serious British guy talking about the Starbucks experience.
