Chain Gang - S6-E3
Plot hole: When all the gang including Arnie leave the flat to go to the restaurant to meet Mr Stavros, Rodney decides to stay at the flat and wait for Cassandra to phone him. The next scene shows the gang all watching Arnie in the restaurant waiting for Mr Stavros to arrive. Rodney is sat in the van with Uncle Albert but Rodney decided to stay at the flat so there was no way of him being there.
The Jolly Boys' Outing - S6-E7
Plot hole: After discovering that there was a rail strike and that they had missed the last bus home, the 27-member coach party all go their separate ways to try and find accommodation for the night. Boycie, Mike and Alan head off together while Trigger is left behind on his own to decide on which direction he wishes to walk in to try and find his own digs. Later on that evening, Boycie, Mike and Trigger seemingly all arrive at the nightclub together. How come? Especially after Trigger informs Del and Rodney that the place where he is staying is different to where Boycie and Mike are staying.
Suggested correction: Maybe they bumped into each other in a pub or somewhere else along the way? It's not implausible for them to have met in a small town prior to arrival at the club.
