I personally would love to see everywhere shut on banks holidays and shut for a week at Christmas again.
Just curious - do you include pubs, restaurants and hotels in that?
Most shop workers I know subscribe to the same argument, moaning about the work they have to do on Sundays / bank holidays but have no consideration for the pub workers.
Going back to the original question, what is not covered is Religious Bank Holidays (Christmas, East Sunday etc). This used to have a significance in the pub trade as you could only open certain hours on those days (Sunday trading from memory) as opposed to normal bank holidays when you could open normal hours.
I don't know what the regulations are now but presume that they have changed with the change in licensing law.
