Here is a a good example of showing loyalty to your customers (Brand to Customer Loyalty). The Cellar Restaurant (in Camp Hill, PA) does this with their "wine lockers" that are labeled and personalized with their customers' names on brass plates. This allows their customers to keep their wine on premises. Or as they put it "Hide your booze here ... Ask your server about our locker rental." It reminds me of the early days of coffee shops that keep their customers' coffee mugs in easily accessible yet within everyone's view right at the espresso counter.
