I work at a bank, and we're typically scheduled 15 minutes or so before opening so we're ready to help the members who come in first thing. If you get there right at 9:00 instead of 8:45 like the rest of us, you'll still be getting your station ready while the rest of us are busting out asses helping members. It's annoying as shit. It's even worse when the lunch coverage teller is late, since everyone gets delayed (or we're just flat screwed if someone has to go to lunch at a specific time)

Yeah, I know more tellers should be hired to make this not a big deal, but that's not what's going on. It's not too much to ask someone to show up when they're scheduled (or, if you're going to be late, at least let someone know)
