Bus operators decide to have additional Bank Holiday
As Boxing Day falls on a Saturday and most people don't work on Saturdays it means Monday 28th December is a substitute Bank Holiday.

However, in my area it seems operators are operating to the following:
December 25 & 26 - No services
December 27 - Sunday operation (on routes where one exists)
December 28 - Bank Holiday operation (on routes where one exists)
December 29/30/31 - Saturday service with early finish on the 31st
January 1 - No services

Surely if they're suspending a usual Saturday service on the 26th, they should as a minimum be running a Saturday service on the 28th?
