We would stay after hours, well into the night, with film nerds and random people with nowhere else to go. Our boss, the manager of the branch was a nuclear physicist turned asylum seeker - who had our backs, brought us take outs and was an all around gent.
This was during college for me. I had some great, interesting, jobs afterwards both in tech and other random things. But I think this will always be my favorite. Those I keep in touch with seem to agree.
