I was assuming that, based on the following, it was already well after midnight:
1. It was 20:15 when we got the initial call;
2. We all were in the middle of other things that we stopped doing to get to our vehicles;
3. Your description of the drive and the traffic along the way;
4. Getting to the club and waiting for everyone to show up;
5. Conversing with Tinman about the job.
Now, it can't be more than 01:00 or 02:00, but that still only leaves about 5 hours before most normal people start work in the morning. Which does give us some time to kill, unless we take your advice and go hit the subway station before splitting up to go to our separate locations.
