People at the checkout in the grocery store who wait to start filling out their check after everything is wrung up and then proceed to fill in the their check register before handing over a check. These same people usually are squabbling about the price of an item, (needing a price check) and also produce 100 coupons half of which are no good.
Drivers that don't let you on the highway as you enter from an on ramp.
Bawling, wailing brats that seem to be in every aisle anytime I go shopping.
Loose dogs in the neighborhood....I can't walk my dogs because there are lot of loose little yappers that think they can take on Dobermans. Just because your dog is small does not mean he can be loose. If my dog is on a leash and your yapper charges my dogs, don't be surprised if the charger winds up dead.
Junk cars and unsightly items sitting on the sides of houses. I wish people would stop storing crap in plain view. Put it in the garage or throw it out!
