You have to remember that many people do not have the passion for good "Q" and many have never tried to make real bbq.
To the those who have never experienced the taste of bbq from a true craftsman, even what we consider the worst of ours, will probably be the best they will ever have.
Many so called bbq restaurants put the emphasis on sauce as the only bbq factor, and forget about meat texture and flavor.
Be happy they enjoyed your "Q" and use what you consider to be "not your best" as a learning experience to make improvements on your next cook.
