We all have days like that. Just be glad it's over and you got through it in one piece
. Imagine if you'd left your wallet at home and didn't have any ID to show the police! Or if you'd run out of gas on the way to the test, or to work. If it's any comfort, it coulda been worse.
I would recommend looking around for a new job, though. Any boss that would cut your hours down to below what you need to live on is not worth working for, because he does not give a sufficient shit about you
