Barry is having a good day, all things considered.
The last dozen passengers he picked up were all on their phones, so he didn't have to make small talk and could listen to music and think about TV instead. One of them gave him a nice tip. And now it's 10am and he's dropped off his last person and he's going to flop on his bed and read comics until it's time to go visit his dad.
And then he blinks and instead of being in his bedroom he is somewhere else.
