i hear you, i got arseholed at my last job (dish pig at a cafe) because i turned 18. So i left, i still go past often and talk to the wait staff and they keep asking me to come back because the others are hopeless and take longer.
And on the P plate issue. Guy use to do that at our school and he'd leave them on his back seat. Until he left it unlocked one day and we shoved all (i'd say 50ish) the plates where ever we could fit them inside and out. He soon stopped.
Women in generally shit me most of the time.
Another pet hate is those people who jump out in front of you when your at speed and there is NOONE behind you. then they continue to take 13years to get to speed .
Another issue I'm having is with people driving 60km's through the 60km zone, then continuing through the 80km zone at 60kms and then into the 50km area at 60km's. Like COME ON god gave us a right foot so we can use it.
