Aah, child-free leisure time! That is my idea of a massive treat atm, and I'm getting some on Saturday!
I don't see anything wrong with"treating" someone to something - the idea of enabling them to have something (whether actually a thing or some time) that they wouldn't take for themselves - but I agree that the whole cultural baggage associated with big man treating grateful subordinate woman is pretty revolting.
I overheard part of a what sounded like a completely obnoxious conversation between two colleagues at work - woman had new ring or bracelet or something, and man was asking if she was grateful to her husband for it, as he was wondering, if it, as a man, it was worth getting his wife something like that. Wtf?? I really hope I got the wrong end of the stick, but I don't think so.
