There's a chance that would be possible in my job as well, but I don't want to take the risk that one of the other three people in the datacenter team beats me and books a holiday on exactly that timeframe leading to my supervisor saying "Hmm, two of you away at the same time is a problem, so no"
In this case, smaller risk is better and since this is the first time I actually have an actual job during the Olympics, I don't want to deal with it wrong and miss out
