I can never understand how Japanese men challenge themselves to younger co-workers and try to hold out and stay up late after a long day at the office. This is so typical of these kinds of oldish salary men seeking attention and more from younger ladies.
The girls get lucky to have some peace and quiet, a snack and an easy night. But what about sleeping in public at a table? That’s not a problem, sleeping in public is not seen as something unusual or odd: https://mesubim.com/2012/12/16/sleepy-sheep/ and it’s quite commonplace even in a hotel lobby. Japanese take advantage of any opportunity to sleep whenever and wherever they can: https://mesubim.com/2014/11/28/sleep-smugglers/
