In my perspective, this is a really undesirable circumstance.
In addition to the typical risks associated with living in a hostel, such as the threat of being robbed or seeing a stranger in their underwear, there is also the risk of becoming ill when staying in a hostel. People who are sick with the flu but continue their journeys nevertheless run the danger of infecting other people on the trip as well as contaminating the accommodations they are staying in.
And exactly the same thing transpired in the case of this person. During his first trip to England, he fell ill with a particularly severe case of the flu, which he believes he caught from another traveler staying in the same hostel room as him. Because he was in such a foul mood, he chose to spend his remaining time in the UK sleeping in the automobile that he had rented.
