Did LS want to get a bus back to the night club? She obviously had money for her taxi fare homewards so was that given to her by one of her friends at the start of that journey or did she already have money on her?
If she did intend to travel back to the night club why a bus? If she needed a taxi she could have easily withdrawn money from a cashpoint at the Clough Road/Beverley Road crossroads? Did she do this?
Another note, Beverley Road looks quite long and straight at this point so she could have conceivably sat on the bench to see a bus coming and then cross the road to catch it.
She may, of course being a student, have been skint and a bus at that point was the only option apart from a nice young man perhaps offering a lift 'on his way home'?
