A new Zealand airport is putting a time restraint on long goodbyes. A sign is posted in the drop-off area at the Dunedin Airport in Momona says, "Max hug time 3 minutes." A photo of the sign has gone viral on social media, with some people calling the limit inhumane. Others are saying the rule should be enforced at other airports. For the people who want more time to hug goodbye, the airport is directing people to go to their parking lot, where they'll have 15 minutes to say farewell.
