United States Postal Service at 240 South Heincke Road, Miamisburg, Ohio.

I'm sorry others seem to have unhappy experiences there - and I don't quite understand it - because I have had uniformly positive ones. I've lived here for 40 years, and the service has progressively improved over the years, to the point where this is my branch of choice. The clerks are always polite, friendly, helpful, and efficient. It's a little slow at peak times, but that's not their fault - I frankly don't know how they keep their cool sometimes. Latest experience: I submitted my passport renewal this week, and Paul, the clerk on duty, was courteous, cheerful, and full of helpful suggestions. And that's usually the same with all the clerks.
