There are two sides to it Daz. I'd find anyone walking into my garden while we are having a BBQ on a bank hol, I'd find that intrusive. Otherwis, why not get a head torch and work nights? I know how it is to be behind on work, but some custies will be put out by us tipping up on that day.
Maybe it's all the little points like this that cause custies to jump ship when another WC knocks on the door. Who knows, but if I don't NEED to work on bank hols, I won't.
