The main worker at the Town Hall is Phyllis the duck. She works both stations at the town hall. She seems happy during the day and really grumpy at night. That's quite unfair because I mostly can only play at night, so have to deal with her being grumpy all the time. She says things like "ugh, quit bothering me." It's wearying to play a game where you're constantly being harassed.
