San Francisco bus transfers
I think I know how the San Francisco "Muni" (bus) receipts work: they tear the tickets on the black lines, and the shortest red bar shows the period you bought the ticket within (+/- 90 minutes). They're supposed to only be valid for 90 minutes, but they're extremely low-precision: they have about a four hour scale (early and late are read as valid for longer time periods). This means that we bought tickets as we left around 1:45 in the afternoon, and Brendan was able to use it on his bus ride home just before 6 pm.
picture: the ticket on the left was bought around 12:30 am; the ticket on the right was bought around 1:45 pm.
