Exterminate!
I did painting and decorating with my brother, one day we went to paint a flat at assisted living facility the place looked nice it was 2 bed room flat occupied by a single guy in his 50s his bed room living room and kitchen were normal and he had no issues from him when painting them.
However when it came to painting the second bedroom he informed us that the fabric of time and space depended on him and we shouldn’t disturb that room.
Inside was full of Dr Who memorabilia; Vhs tapes, dvds, posters, as well as a life sized Dalek he was rebuilding, the guy thought he was the real Dr Who but was super nice we didn’t even end up painting it as it would of disturb the Dr’s work that and there was no way we could empty that room to paint it.
