i dont use any of the exelby sites except to fuel up, and thats mainly at whitwood cos i am on containers.
i find the staff ignorant, ( especially the irish bloke ). the meals are crap and expensive.
i once was going to have a coffee but the dirty woman seving me picked her nose and handed me the cup with her fingers around the rim. ( dirty cow ). you guessed it i swiftly walked off. never used them since and never will.
i find the A19 sites very good and am in there most days, get on great with all the staff except the big woman on the northbound side, what an ignorant cow she is 
How true about the uniqueness of Londonderry.If ever a building had a soul this place would be way ahead,it’s very existance is a rebuff to the sterile,soulless nature of modern day uk and i’ve never been happier than knowing a hearty Londonderry breakfast is on the horizon.Bloody love the place even the local tornado jets enhance the experience.Hope it survives the A1 upgrade.
