Twenty minutes between trains at 10pm is wild. I knew service got worse at night but I figured it was maybe 12 or 15 minutes, not double the daytime wait. And yeah, vals38, your friend waiting 25 minutes makes me feel a little better about peacing out at 18, but honestly that's such a low bar. The part that gets me is there's no heads up anywhere, no sign saying hey, this is the last frequent train for a while, nothing. You just stand there watching the number climb and find out the hard way while your phone battery dies. My rule now is anything over 12 minutes after 9pm and I'm opening the Lyft app, the savings aren't worth losing half my night on a cold platform.
