Recently I was on a bus with a buggy, along with another woman with buggy and child. When a group of children from Rainbow holiday club tried to get on, one of whom was in a wheelchair, the driver refused to let them on. This was met with an argument about wheelchair priority from one of the carers. The driver told her that wheelchairs no longer have priority on buses. The other woman and I were dumbfounded as thios was news to all of us, and we both chose to disembark to allow the children on. I would have folded but was only two stops from home.
On the flip side, I was left at the side of the road by at least four buses that refused to stop (some waved, some ignored) as I tried to get to hospital with a two-year-old who had broken his leg (he had fallen asleep as I checked his leg & comforted him). I had to go home and wait for him to wake up so I could leave the buggy at home & carry him. I haven't bothered complaining because these incidents are too frequent for me to believe they aren't sanctioned from above.
