Out chasing bad guys? Was this a cop? Betty never really had any issue with cops, persay, but she didn't particularly care to tangle with them either. Maybe there was some law about feeding the ducks she didn't know about. Perhaps it was best to ask, just to be safe.
"You part of the local law enforcement?" She asked as politely as possible. Really, for as rude as it was for him to be laughing so openly when it seemed like he was laughing at her, there was little point to be rude back at him.
"But I know what you mean, little work to be done. I feel the same way, I should feel guilty for not doing more, but I don't." It was about time she got a decent break, anyway.
