If i'm out for 12 hours plus, drinking isn't usually an issue - pubs have loos anyway - the worst is waiting for buses for 30 minutes or more with no loos within easy reach - some buildings have lous loos as well, namelythe Arndale Centre, Trafford Centre, and the worst - Central Library - the loos there are always closing for cleaning when you need them - there's a public loo at the town hal and I sometimes use that instead of the library ones - the city provision of loos is a joke.
