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.
