I don't really think it matters why you asked someone on date if you go on it its most likely because you are seeking some sort of benefit. I remember when I was younger girls would occasionally go on dates with me to get free dinner or free booze. They didnt really have any interest in me and according to your definition that would have put me on the receiving end of asshole behavior. Despite that I always got something out of it otherwise I wouldn't have gone. A date was always good for a self esteem boost, minimal social boost, practice and sometimes I even got introduced to other friends that liked me more. Reflecting back they definitely got more out of it than I did but those dates were still preferable to not having any dates. Net effect was that both people came out ahead although some people did better than others.
