I changed DS earlier in the car, back seat where his seat is. He's 5. He had to stand up and it was over within a few minutes. It's tricky but disabled toilets are often so rank
AIBU? I was approached afterwards and told there are toilets for that you know! I said they're dirty. She said 'yeah, it's a toilet?'
I said where's your blue badge then? Just to get at her, I know it was petty 
She said 'I don't need one love, I'm 65!'
And she slammed the door
