One time I was asked to come in on a Friday for a full shift starting at four in the morning to help ESFS and since I love being backroom because it's a nice break from guests, I excitedly said yes. This was when I wouldn't really review my schedule I would just check the start time of the shift the day before.
Come Wednesday night, I realized I closed Thursday and I was going crazy trying to have someone cover my service desk shift for that night but couldn't find anyone so I ended up just working both shifts. And for some awful unknown reason, I couldn't sleep well so I actually went more than 24 hours without sleep. Luckily, we were drowning in so many orders, I was running on pure adrenaline and didn't even notice how tired I was. Lol.
