at the supermarket today i recersed out of parking space and turned to face the exit which meant i was also facing the entrance doors of the shop where there are double yellow lines. there was a car parked there meaning i couldn't pull out and another car couldn't get past. the reversed and took another route but there were other cars behind me so i couldn't reverse. the woman in the car was looking and looking away so she was aware i was there. i wound down my window and beeped the horn to catch her attention. she opened her door and before i could even ask her to move she shouted "disabled can park wherever they like". and closed her door. her car was switched off and tehre was no-one getting in or out so i presume she was waiting for someone. i shouted over that she was causing a problem for other drivers and she opened her door again, i said " could you not just move a bit further up" which would leave the junction clear. she just said no and shut the door. by this point one of the cars behind me had reversed and the other was starting to aswell so i just had to wait and do the same. all the while this lady sat on. there were 6 empty disabled parking bays that she could have used and then pulled up at the door to collect her passenger.
was i being unreasonable? or is she actually allowed to park there?
fwiw i do think she could have been a bit more mannerly about it but perhaps someone had already said something so she had her heckles up.
