That is so wrong, I know its the case but I don’t agree with it. You are correct, anyone with a blue badge can park there. What makes things worse is that some council authorities charge you for installing it, but again, anyone can use it with a valid blue badge. Most of the time, I think people are genuinely courteous but as you highlighted, clearly there are people that just don’t care about anyone else other than themselves! Its a shame that society has come to this and people feel its acceptable to display that level of abuse towards others.
