(pre-thread warning: I'm a bit of a grumpy arsehole most of the time)
So, about two hours ago, myself, DH and DD (6 months) went to tescos. Headed for the parent and child spaces, but they were all full. I saw a couple, probably in their mid-30's loading their shopping into their car - not a child or car seat in sight. So DH pulled into a space just across the way from them. I made a big show of struggling to get DD out of her car seat in the normal sized space, and as we walked past I said "nice to see you struggling to get all your kids into your car in that massive space" 
The man didn't know what to say, and the woman just put her head down and pretended not to have heard me.
Was I BU? Or does everyone else get The Rage when childless people park in parent and child spaces?!
