Not sure if they're all minor, but...
Couponers who have 300 coupons but are only going to use 43 of them but expects the cashier to sort them out. I swear, we need a mechanical coupon sorter at the checkout line that automatically accepts a bag of coupons, sorts them out, applies the correct deduction to your total and spits the rest back at you.
People who stand in a 10 items or less line with a cart full of groceries. I guess they intend to count the entire cart as just one item.
Parents that shouldn't be parents! I recall a very cold day earlier in the winter and I ran to the local grocer to get a few quick items. There was a man who had set his ~ 1-yr-old son down on the cold floor and was upset with the boy because he started crying. The kid was jumping up and down because his bare feet were cold. The small boy was wearing light pajamas and the man was wearing a parka. I was cold myself. The store was cold.
Parents that are distracted while trying to feed their small child from the table and end up burning their mouths because they don't blow the food on the spoon and check it for temperature.
Parents who attempt to quickly warm a bottle of baby milk in a microwave and end up scalding the inside of a newborn's mouth.
Parents who leave their children and animals in a hot car.
Pet owners who leave their pets outside all day in the middle of July with no water, or an unreliable water source.
People who have no problem exercising their right to vehemently complain about politics or the election but refuse to exercise their right to vote thus exercising their right at what they say to be heard by those who count.
