I was on QF94 in F recently. A few hours prior to landing, there was a lot of cabin crew activity due to breakfast, clearing beds etc. I was still trying to get a nap after breakfast. I noticed a lot of creaking as they moved up and down the aisle. I'm not sure if this was the floor itself, or if it transmitted into the cubicles, causing those to "flex". I don't think they were being overly heavy in their steps, but not really cautious either.

Does anyone else notice that? A minor irritation on an otherwise near perfect flight.
