There are trains from London Bridge to South Bermondsey on saturday ( and back for the clever fuckers amongst us), for anybody travelling that way.
FYI
Having worked as a driver for LUL for the past 23 years (now retired at 53) I know how ASLEF (known locally as Spaslef) & RMT reps operate and I genuinely despise those cunts for a myriad of reasons that are too numerous to go into.
