This technology saved me an hour wait at Krispy Kreme one night a few years back. They had one of their BOGO dozen deals and at 8:30PM Google said they were slammed so I didn’t go. An hour later it said the line slimmed down and when I got there they were serving the last three customers from a huge rush. I mentioned why I waited and the staff was also confused how Google knew they were so packed just an hour earlier.
