We just came across this amusing post via The Muni Diaries' counterpart in commute-blogging, The BART Diaries. Apparently this blogger *really* hates Muni, and here are her highly generalized observations as to how Muni riders have fewer manners than BART riders. She has seen/heard Muni riders:

1) Smoking marijuana right on the station platform
2) Spitting on the platform
3) Blocking the doorway
4) Talking extremely loudly on cell phones
5) Loudly telling offensive stories about drugs and sex
6) Urinating or otherwise soiling train
7) Putting feet on seats
8) Letting animals sit on seats
9) Calling me a "fucking bitch" and threatening to kick me when I asked the man to pick up his dog.

She was also appalled that a police officer refused to help her after the incident described in #9.

We believe we can cite having witnessed all of the above on BART on at least one occasion, except perhaps letting an animal sit on a seat or being called a fucking bitch, so we don't think BART is all that prim and proper either. Have you smelled that carpet lately?
