New Jersey is rough

At the airport here at 6:30am and everyone just communicates by shouting at each other, from TSA to Starbucks to airline employees. Just heard a checkout out lady in a store mutter “Have a nice day” under her breath. The customer didn’t hear her and said “WHAT DID YOU SAY TO ME?” She shouted back “HAVE A NICE DAY! HAVE YOU HEARD OF THAT?” This seems typical here. It’s exhausting.
