Leaky faucets; squeaky cabinet/door hinges; door thresholds that let water inside only when it's a huge storm with heavy winds and rain; cars that only start after several attempts; my blog host which requires several failed attempts before uploading an image; grocery stores (Kroger and Harris Teeter, for two) that have only a single checkout line manned by a person — often new or old and slow — so as to "encourage" customers to use the many self-checkout stations; credit card readers that require several attempts before acceptance; gas station pumps which increasingly require more personal information before allowing you to put the darn nozzle in your car; phone and tablet touchscreens covered with fingerprints and skin debris and dust etc. but still quite usable; eyeglasses with the same issues; clothing you know isn't fresh but that's still wearable if the alternative is doing the laundry; running out of coffee beans and using instant as opposed to taking the time and effort to buy fresh beans.
I'm sure others here have equally amusing exemplars....
