Not working late, but I had to get a 6am train on Friday to make sure I was at a client's office for 9, because there was a big meeting at 10. Then on arrival I got told I wasn't required for the meeting. Later a 3pm meeting was slated to last an hour, but actually went on til well past 5, so I missed my train home. The worst thing was my involvement in the meeting was negligible. So as I said not working late, but a bit frustrated to have traveled a 6 hour round trip for no reason.
