Actually it could be. Let's say there's this beacon software that lets you look a bit into how someone interacts. Say you get to know what 'spending tier' they're in - high, medium, or low. You also get to see how much 'social influence' they have - again, high, medium, low. Why would you give a free hot dog to someone in the low-low tier? You probably wouldn't, but right now you have to carpet bomb free stuff. Select who gets your free stuff so you can maximize your influence. Have it pop up when someone is walking down your street, at a particular time of day.

When the big spender with a lot of friends walks by, drunk, at 2:30 in the morning home from the bar, send him a free sandwich coupon when he hits your street. Throw in a bag of chips and a pop, make it 'special'. Perfect advertisement to target the perfect people.

Your software lets companies deliver freebies to 'important' people when they're nearby. Have some automated identity finders - find them on fb, g+, twitter, see how much reach they have. Give them some free stuff, see if they tweet about it, put them a bit higher in the ranks because they gave a good word (or any word at all).
