I am on business in Manchester soon and wanted to know if there are any stores, shopping malls or other large public areas or facilities with a single toilet for both men and women? By this I don't mean a unisex toilet with multiple stalls and sinks where men and women can go, but a store with just "one bathroom" for everyone, male, female and disabled, with just one physical toilet in it? I am asking because I do not feel confident using a female bathroom in case someone talks to me, and I'm sure I have seen "one toilet" places before, but can't recall where.
