I haven't been to SF so don't know if the subway has toilets in it. It's said that you can judge the civilisation of a city by how available toilets are. In Taipei the metro stations all have toilets in them. In London very few stations rarely have toilets. Of course, this is comparing an new to an old system. If the SF system has no toilets then maybe this would explain things ?
