Restaurants and venues could gain some additional traffic for off-peak hours using these incentives -- sort of a late-night happy hour that requires the group to check-in through the app. Pretty smart.

And I think it's inevitable that an attractive or high-spending group would receive favourable "bids" from venues. That's happening already in club queues around the world, but at least this way you might waste less time waiting or at least get better treatment at a second-tier club than be snubbed at the most popular spot. Ugly reality of trends in that world, maybe.
