Buses running late, or not turning up has been happening for years in fact it would have been happening since the bus was invented and it's not a problem unique to Go North East. Least in the days of modern technology you know if it's going to turn up or not. So no matter how many letters you write to Nexus etc whining that this bus was 1 minute and 25 seconds late, it won't change a damn thing. Anything and everything can make a bus run late whether intentional or not. Just accept the fact it's something you cannot control and move on, trust me from my own experience it's less stressful.
