I bought the Newsweek magazine about lego (June 2024..pgs 94 and 95). This edition showed multiple pics from two sets: lego airport and a hamburger stand. These sets show manners that have either eroded or that I may have just assumed were a given.
4 things in particular come to mind.
1)smoothly going through airport security without much hassle and assuming you were reasonbly safe
"The etiquette of holding open public doors is unnecessary"
4) (Below)
People getting good service and workers connected to customers. Customers were happy with the goods received and treated servers and staff with respect...
For these 4 reasons I wish I was back I'm the 80s!
