I just say, "Could I have change for a 20, please?" If I'm at the till, there's not much worry I might be asking the random customer behind me. Especially when the cashier is the person I've already been interacting with, by then.

They make you wear a nametag because at some point someone presumably decided this was friendlier, same as they somehow decided calling customers by (first!) name made them feel valued. First-name exchanges between people who are essentially strangers always feel awkward and over-familiar to me and I avoid them as much as I can.

Even excuse me? Hm. 'Excuse me' is what I generally say if I need someone's help; is there something you prefer?
