Sometimes I'm not quite sure whether to call an unaccompanied woman "miss" or "ma'am". If they're clearly young then it's an easy Miss, but if it's in that grey area I'll just stick with the miss because that has a better chance of being flattering. If they're clearly a bit oilder I'll load up the ma'am because they probably appreciate that respect. I guess? Anyone feel free to correct me if I'm wrong on anything
