Here is an interesting example of incentivizing socially conducive behaviors. Eva Restaurant in LA, a chic upscale "family style" restaurant in LA offers patrons a 5% discount for handing over their cellular device during the meal.
I think this is an awesome win-win-win situation where the restaurant generates interesting buzz for incentivizing their patrons to have a more intimate experience. In addition, patrons will be more focused on enjoying not just their company, but the food and decor that has been painstakingly arranged for them.
Another way to think about this set up is that patrons are earning 5% per meal to focus more on the product being offered and hopefully convert into fans who spread the message.
If you're in the LA region, I'd definitely swing by and give this offer a try. The offerings look absolutely divine.
