Possibly the biggest offender when it comes to destination screens in the North East is Hodgsons Coaches, where of the four buses that are normally allocated to normal service work, three of them have no working destination equipment whatsoever whilst one MPD has a front LED screen but side number roller destination equipment.
S24 BUS - no working equipment

MUI 6061 - certainly no front destination equipment

745 DUY - front screen, side roller

Believe that the other MPD they have doesn't have working equipment either.
Another concern with them is a lacking of ticketing equipment, pretty sure only the Solo has a ticket machine and according to Alex Garwood on Flickr, it doesn't appear to work. Everytime I've been on one of their buses they appear to have been noting passengers of using their services by writing it down on paper.
