@Ninji I went in to use the toilet when I was exhausted from walking around the city all day & it was like insanely crowded and the toilets were about as far away from the entrance as it was possible for them to be. One of the escalators was blocked off & the adjacent lifts never seemed to turn up. And then trying to get back out I got lost and ended up at a dead end and had to go through Primark which has a Greggs in it for some reason???
