To answer your question, “Oh is that how it works now? What happened to line etiquette?”
Well guess what – if you’re next in line, and the gal calls “Can I help the next person in line?” and you don’t notice because you’re too busy being Chatty Chatterson to pay attention even though YOU’RE THE NEXT PERSON IN LINE, then it is YOU who have broken line etiquette because now the gal, and I, and whoever is behind me are all waiting for your sorry ass.
So yes, that IS how it works now. Make all the snarky over-loud comments you wish; I cut, and my frostie was no less sweet for it.
