I have three scenarios for you here. Both I have seen happen in the last month.
Scenario 1:
Rural area - 3 buses into town a week which is a 45 minute drive away. Lady gets on minibus type bus with pushchair. There isn't a sign that says wheelchair users get priority. It's just your bog standard Maclaren umbrella fold. You can't fit a buggy on the luggage rack (I've tried before when I had DS with me) so if you fold it there's nowhere to put it. Halfway into the journey a man in a wheelchair wants to get on. He doesn't even ask the lady to move he just goes back home The lady has paid her fare so probably didn't want to get off. She also would have been stuck in the middle of nowhere for 5 hours before the bus home came.
What do you think about this?
Scenario 2:
Man with non-walking child in a major buggy is already on the bus. Journey is about an hour long. A wheelchair user wants to get on. Driver says sorry we've already got a wheelchair user on (meaning major buggy) Wheelchair users huffs and puffs a bit but doesn't argue. Should the wheelchair have taken priority over the major or not?
Scenario 3:
My friend who uses a major buggy for her DS was waiting at the bus stop. When the bus came there were buggies in the wheelchair space so the driver wouldn't let her on. She explained that it was like a small wheelchair but still he wouldn't let her on - first come first served you see.
Should she have got priority over the buggies?
