Some people are just rude and ignorant. I'm a wheelchair user and I was unfortunately in a situation similar. I was shopping with my husband and suddenly needed the toilet but when I got to the disabled toilet, it had been partly used as a storage area, with large plastic bins in it. There wasn't enough space to manoeuvre my wheelchair inside, so my husband helped me to walk the few steps from outside the cubicle to the toilet. It's severely painful and difficult for me but it was the only way I was getting to a toilet. It meant leaving my wheelchair unattended outside the room, as I need help from another person while using the loo.
On coming out of the toilet, about two minutes later and being supported by my husband again, I was desperate to be seated in my chair, only to see it wasn't there. A young boy of approximately 11 to 13 years old was rapidly wheeling in it down the long corridor and trying to tip it backwards and balance in it. Meanwhile his mum was stood there watching him, carrying a toddler on her hip. She was waiting to come into the changing room to use the baby change table, I think.
When I asked the boy to please stop playing with it and bring me my chair back, the mum looked at me and said "Well you shouldn't have f**cking left it outside if you didn't want anyone to use it!!"😱
The boy smirked, really slowly wheeled it back towards us, got out and then deliberately tipped it over backwards with a crash.
The Mum marched off with her kids, giving my husband a long mouthful of abuse, when he'd said that a wheelchair isn't a toy! She yelled at the top of her voice "Disabled C*nts like should stay home and stop getting in everyone's way!!"
By this point I was struggling to stay conscious from the pain and my husband couldn't let go of me to be able to right the wheelchair and get me seated. Luckily another customer had seen and heard the problem and came over to do it, before I fainted.
I was in too much physical distress to be able to go get help from a security guard or even process what felt like hate from her. I was more relieved that my wheelchair wasn't damaged because it's expensive and custom made.
