It's not really even about power: if they're a colleague or your boss, it's inappropriate too. I've never heard of a man being ignorant enough to hit on a female boss, but it wouldn't surprise me. Even if people don't follow the platinum rule, they should surely recognise that there are interactions they would have a problem with. The people happy handing out "hugs" to people they are attracted to are surprisingly unwilling to receive them from people they find unattractive. Everyone should be given social space until a mutual agreement that something else happens. This is especially important if there are significant cultural differences between people.
