Well, the post office is probably not the place you want to go if you want to be infused with patriotism and a renewed sense of vigor.

Summary

This quote appears to convey the idea that one should not expect to feel a strong sense of patriotism or excitement by visiting a post office. The post office is often associated more with administrative tasks such as mailing letters and packages rather than evoking emotions of national pride or motivation. It suggests that there are other places or experiences that are more likely to inspire such sentiments.
