Episode #3.1 - S3-E2
Continuity mistake: When Geoff is shouting at Donald, Jacqueline and Noreen for not getting anything right at crosswords, the people who walk behind them in the background keep changing between shots. It starts when Donald says "Quite saucy for a cartoon", a female hotel worker walks past them in the background. We can see the woman walking in the background when Geoff says "You're all sitting here talking rubbish". About 2 shots later, the female worker in the background is now much closer to them but still walking off. Then in the shot where Geoff says "Course it matters!", a male hotel worker and a woman in a bikini behind them walk past them. About 3 shots later, those exact same two people are seen walking past them again.
