I want to know the answer to the following question:
This caused a stir in deciding who should enter first and who should do what?
All the background I'm provided with is that "In Lifted: A Cultural History of the Elevator, author Andreas Bernard documents other social impacts caused by the modern elevator, including thriller movies about stuck elevators, casual encounters and sexual tension on elevators, the reduction of personal space, and concerns about personal hygiene.". Is that enough to answer the question?
