Because outside of the square is a desolate wilderness apart from four places - "up West" where they shop but don't bring bags back, Milton Keynes which is so cheap a taxi driver and gobshite can afford a four bed with a loft conversion, Maaaaanchester and Noocarstle (where Michelle went to college many years ago). Nowhere else exists although Birmingham is somewhere recently added to list of "other places". Lola is better off up there - cheaper housing, nicer people, fabulous city, brilliant support for the local football team, decent shopping, fab nightlife and places to visit that are stunning. Weird exit though.
