Have you been to Trader Joe’s? Their cashiers are all late 20’s - early 30’s pretentious hipsters who act like they make loads more money than me & im just some peasant.
The Trader Joes out here has careful meticulous baggers, regardless of their age. The other major grocery stores, Shop Rite, and Stop n Shop have crappy cashier/baggers, and it's at those store where I happily head to the self-checkout line...
