I haven't really experienced it before, as a professional middle aged woman living in SE and working in London, I find my experience and opinions are sought after and valued, both socially and professionally.
However, I am currently walking a long distance trail in the North of England, solo, and receiving very different service to guests in couples, especially I find, from women.
They do what they need to, there's nothing to actually "complain" about, but they're very blunt and unsmiling, whereas they're making an effort to chat, provide the famous northern hospitality and be friendly with other guests.
What's that about?
