I've got one bungalow that should take 15mins but takes 35 because of plantpots which may I add contain nothing more than soil, moss and plants that died before Stalin. I also do another house where the owner trains police dogs, ok, so police dogs are supposed to be calm, obedient, yeah right, they'd tear the nuts off you without an invitation, he also has his own silent attack dobermans, 3 of them, well scary.
