Entering a vast museum complex, whether it be an institution like the Louvre or the Met, overwhelms the average tourist. They’ve most likely never been to this museum before so they grab a map and study the location of must-see pieces and exhibits. Racing through endless galleries, sometimes two or three times because museums tend to be maze-like, the visitor battles crowds and attempts to catch their breath before they’re on to the next painting/ceramic/sculpture/wood block print/etc. Consults map. Stands in front of work of art for fifteen to thirty seconds. Takes a photo with phone. Checks to see if there is an outlet in the deserted gallery. Maybe an attendant or guard won’t notice the tourist plugging the dying phone into the wall. Sit on bench in corner and look at display case full of priceless objects while phone charges. Review map one last time.
