If I'm going to a session, I'm not gonna bring a bottle of red wine in any event, cuz, as discussed in another thread, red wine doesn't seem to me to be very good to drink by itself.
If I'm taking someone out to dinner, prostitute or not, I'm gonna order a good wine. Cuz I've got to drink it, too.
If I know someone and she invites me over to dinner, I'm gonna bring a good bottle. For the same reason.
