From a WC, I would expect fast communication, answers, for him/her to do the leg work (via calls, emails etc) in a timely manner, organization and speaking with enthusiasm. I know it's not a deal breaker, but everytime I open my email to see someone talking with !! like they are excited about MY wedding, I am put at ease. =) If you are NOT LOVING your WC, I'd request another. Key people play important roles in the planning of your wedding, if they are not as efficient as you'd like them to be I would find someone else immediately/
