Well, the consensus is that a twitter-life can emulate real life and be a bit cheeky. Tweets don't want to be set in the corner with their "I'm a Pro" cap on. Content Snobs disagree, and that's fine too.
We also discussed the need for social media for every business size and type. The unhappy customers are already bashing your establishment, whether you are checking on it or not. The lookout social media engagement provides is the best way to be able to fix the problem and also to show the world you fixed it. Can't argue with that.
