I was a Private Investigator for a few years a while ago. 99% of the cases were Worker's Comp related, with the employer not believing that their employee was injured, and was just milking the system.
Every now and then, I'd have to do surveillance on the weekends; it didn't happen that frequently, but when it did, it fucking sucked.
One particular case, my boss told me I would have to do Saturday surveillance, and gave me Friday off to compensate. I wasn't planning on going out, but a close friend called and suckered me in to going out with her
Well, we go out, and I get wasted. I'm supposed to be at the subject's house at 6:00am, but I wake up at like 9. When on surveillance, I'd have to call my boss to check in when I arrived, and every subsequent two hours to give an update.
Well, I obviously missed that. My boss then called shortly after I woke up and I bullshitted that I was actually at the house and that nothing had happened. He wondered why I hadn't called to let him know I was there and I made something up about my phone being dead and that I needed to recharge it, or something.
For the rest of the day (surveillance was 8 hours, typically 6am - 2pm), I'd call and give him updates, saying nothing happened, etc. while nursing my hangover.
Unfortunately, with every case, you have to write a report. They are pretty boring, consisting of nothing more than "7:43am - subject seen walking from car to front door", shit like that. I had to make up the entire thing for that day, and considering the fact we bill people for this time, I was already being a complete shithead.
Turns out, the subject had a doctor's appointment that day at 11:30am, meaning I should have seen the entire thing happening. When doing surveillance, you have to film every last thing a person does; if the person is visible, you have to be filming. If a person gets in their car, you have to follow, and if they get out somewhere, you have to film them, no matter where they are. In the past, I've followed a subject in to a doctor's office, making up a reason to stay in the lobby as long as the person is there (I had a backpack with a pinhole camera on one of the straps, allowing me to film). I usually just talked to the receptionist about medical insurance or something as an excuse to stay.
We found out about the doctor's appointment from the subject's employer. When my boss looked at my report and noticed that I said nothing was happening at 11am or so, he asked how I could have missed the person leaving their home.
Welp, he wasn't too thrilled. I could either say I missed it, which would have been me saying I am a shitty PI, or admit that I was never there to begin with. I probably should have said the former, but I admitted I was never there. Hooooly fuck, he was justifiably pissed.
We ended up not submitting the report and told the employer that we weren't able to do surveillance that day for some random reason. I was forbidden from surveillance for about a month and had to sit in the office doing menial BS work the entire time.
I should have been fired, but regardless, I always felt guilty for doing that to my boss as he was such a great guy. He and I had a great relationship.
Things went back to normal, but I still look back and wonder what I was thinking.
