People who won't say "thanks" when you hold the door open for them.
Drivers who won't acknowledge you when you pull over to let them through.
I've encountered one each of these today. It's doubtful that either of these two ignoramuses are reading this rant, but if you are - I'm not your fecking servant, OK?
When I set up this blog it was not my intention to write about stuff like this. Most people, you would think, have been brought up with some basic manners. There's not usually any excuse for not nodding/smiling when someone holds open a door for you - unless of course you're on an aeroplane in mid flight & not wearing a parachute.
Likewise, although it's probably not mentioned in the Highway Code, most drivers know when to say thanks in some way when someone pulls up to let you out of a tight parking space. You have to be a bit careful though - some people leave it right until the last moment to hold their hand up when you've let their oncoming car in ahead of you at a tight spot in the road. Many a time I've been about to give someone the bird, when they've smiled & nodded their thanks virtually as our windscreens are parallel.
Some might say that there's more serious issues to be concerned about, but my argument would be, get the basics right at least.
