Ma and Pa Constantopolous popped to the town today. I say popped... 
Their plan was to get a 4 to the Galleries and then an X1 to Newcastle. Almost 3 hours after setting off, they ended up in Newcastle.
The return journey was just under 2 hours. That was using a 21 and a 78.
They had no idea it was a Sunday timetable and only knew after overhearing someone whilst they were waiting for an X1 in a 'mile long queue'.
They're disgruntled pensioners who still have two cars, but thought it would easier getting the bus to and from the town. 
Not sure they're in any rush to get the bus again after todays experience.
