Not read the rest of this thread thoroughly so apologies if repeating other irritations.
Peope who use 'Pay @ Pump' petrol pumps then go and pay at the kiosk whilst I sit there with a full tank of fuel, paid for at the pump, waiting for them to get back to their car.
People who, after paying for their fuel, spend several minutes in their car farting about with receipts, loyalty cards, radios, makeup, etc. Ideally the car should be already moving before the door is closed!
Loyalty Cards.
Oldies/Disabled drivers using Parent and Child
parking bays, especially when there are available disabled bays, but they're further away from the supermarket doors.
Parking in a space comfortabley big enough for two, but
parking slap bang in the middle so nobody else can park there.
Somebody mentioned bag packing kids. Couple of years ago my local Morrisons had kids packing bags on Christmas Eve!
Halloween. I spend 364 days of the year telling my kids not to talk to strangers or accept sweets from people in the street but for one night of the year I'm supposed to encourage them to do it.
Cyclists ignoring traffic lights because they clearly don't apply to cyclists.
Cyclists complaining about motorists (especially after being hit by a motorist at the lights).
Teenage 'nobs' who walk down the middle of our road even when a car is waiting to get by because they are so 'ard. I really feel like testing which is 'arder - the teenage scrote or my bumper.
Doctors receptionists. Just how long do they need to go to medical school to establish if you're urgent or not by the sound of your voice over the phone. "Can give you an appointment next Thursday" - "To be honest love I was hoping I'd be feeling better by then".
To, Too and Two.
There, Their and They're.
People posting on a thread on a forum without reading everyone elses posts to see if they're just repeating what somebody else has said.
