From restaurants to schools to churches to COVID-19 vaccination sites, people wait in queue lines in myriad settings. If you’ve ever been on a call with customer service and been placed on hold with a voice telling you, “Your call will be answered in the order it was received,” you were technically in a queue line-just not a physical one.DMVs and other public sector services use queue lines to manage patrons.Amusement park guests often wait in long queues for popular rides.

Airport travelers deal with multiple queue lines, including checking in their luggage with an airline, waiting in a security line to have their ticket and ID checked, having their carry-on bags and themselves scanned, and waiting to board a plane when their zone is called.The drive-through doesn’t eliminate the queue-you’re just waiting from your car. Bank customers may wait, especially at peak times, in a single queue line for an available teller.Some retail businesses, such as bakeries or deli counters, direct their customers to take a number and wait for service until that number is called.
