Hahaha! I laughed there, honestly i wouldn't have taken it as a threat anyway .Fair enough! Where do you live? (This isn’t a threat, perhaps users in your area are more discerning than in Donny)!
I live in Aberdeen. It tends to be the OAPs but i've heard plenty of people complain about the ride quality on certain bus types. Streetlites being the main culprit followed by Stagecoach E350Hs and E400s, although with the latter it's down to poor maintenance rather than vehicle type.
So they do, my mistake...Cummins have two sites in Ward Park Cumbernauld, one is a workshop (pictured in the media) and a production facility on the opposite side of the M80.
I would be surprised if the workshops were to be closed, they are quite busy.
