Part of my job involves listening to a fair amount of this. Today I listened to a man who called to complain that teenagers are not polite on buses, that they do not give up seats to seniors, that they put their backpacks on the seats and look at him in disrespectful ways. None of these are things we can fix, for legal and practical reasons, but of course, I still get to listen sympathetically before getting him off the phone. I also listen to complaints about how when it rains, the rain blows into the bus shelters in Daly City, so that shelters should always be built facing away from the wind, and about how it's unfair that the bus system does not serve every street in San Mateo, because seniors don't just live on one or two streets, and it's mean to make the walk to bus stops more than 1 block away.
