Confessions of a Window Company...
If you visit the Halifax Trade Windows website, you'll find it is a hugely unremarkable place. However, when they run adverts, they are a lot more saucy.
As you can see below, they're using the kind of chat and imagery you might find in a London phonebox, with risque chat about PVC and all manner of whipping and bondage stuff.
Full marks to anyone who enjoyed and spotted 'Sod House' as well.
