That bartender's number might be onto something. I read a piece a while back where a matchmaker said most people don't really show who they are until around date 6 or 7, once the nerves wear off and they stop trying to impress you. Three dates in you're still on your best behavior, ordering the nice drink and laughing at bad jokes. By seven you've seen them tired, annoyed, or bored and that tells you way more than any fancy dinner. So yeah, the bartender in Austin sounds like he's seen enough train wrecks to know.
