Offensive? Maybe....
Couple years ago there was one of these candid camera shows on tv. They had a 737 (GERMANIA) with no seats (maintenance event, btw) instead on the ceiling a pair of handrails was installed, like in a bus.
They offered a refund of 25 Euros to do the two hour trip. Out of about 100 pax only 5 denied.
