wishingonastar.....oh yes, we were instructed to knock twice, and even call out. Sometimes people won't answer or didn't hear...can't really yell too loud because people across the hall complained you were waking them up!!!!
I have walked in on several people, even after knocking and calling out....it was very embarrassing for both them and me!! Sometimes you had someone who got a kick out of seeing your expression and would purposely drop their towel or continue with their "playing", etc. Some guests would even answer the door naked, and not think anything of it, just standing there with the door open and letting it all hang out!!!(men and women) People would be in the tub and ask you to bring in the towels to them....
We also had a house "gentleman of the evening" or daytime for that matter. This great looking young guy would always be seen entering or leaving a room with a mature older women. I doubt they were all his aunts!!!!! This went on for over a year!!
I was glad to leave that job.
