1. Cheap cotton stretch shirts/dresses that look nice the first time you wear them, but totally loose their shape after one wash or two.
2. Driving down the road, then slowing down gradually, putting the blinker on to turn, then having some idiot swerve around you honking like mad at you for slowing down to turn, as if you'd just suddenly slammed on the breaks with no indication whatsoever that you were going to turn. Keep your eyes OPEN people!!! Red break lights means the person in front of you is SLOWING DOWN. A blinker blinking means they are TURNING. Get it? Got it? GOOD!!!
3. Trying to find shoes/sandals/footwear for feet that are probably a size 9 or so, but have toes so long they bring it to a size 11. The arch is never in the right place, the toes are often squashed, and size 11 thongs have your toes overlapping the front, with about an inch of space in the back, because the thong isn't back far enough.
There are more, but these are the ones bugging me more recently.
