Absolutely agree and I think airline check in staff should make overweight people sit next to each other as well so they can appreciate how much space they are taking up and how uncomfortable that loss of space is in already cramped conditions.
We all have choices in life and it is about time people started HAVING to take responsibility for their lifestyle and its consequences.
Yep and people with one eye should get a discount at the cinema especially if its in 3d.
This is not completely new. in the South Pacific many of the islanders think being obese is a status symbol. they are charged for 2 seats everytime they fly.
I think its reasonable but only if those decided upon to be wankers by me pay triple - that would quadruple revenue
You might be surprised to know that an airliners seat is only tested and approved for a load of 75kgs. Obviously the seats regularly carry much more than that but the design weight is for just 75kgs.
What you won't be surprised about is that in aviation matters weight is EVERYTHING and it would not be productive for the manufacturer or the operator to reduce the number of seats by making each seat bigger. Reducing seat numbers means increasing seat prices and in this economic climate won't work.
They should charge by the foot at the cinema too to compensate the shorter for having to sit with a restricted view behind the taller.
I don't think it has anything to do with not " liking fat people " at all.
It is simply a way of trying to get extra money.
Do not bank on the trains or buses doing a similar thing in the future.
lots of sexy shoes
