The rude behaviors that really piss me off, in no particular order. People who talk in the movies. You're not in front of your TV. You're in public, remember? People who eat in live performances. Those people are actually alive up there on the stage. You're not at the movies where you forget that you're not in front of your TV. People who don't pick up their dog's poop. Definitely grounds for a $50 fine. Spitting in public. This is what separates Man from the llama. Littering. If everybody threw his trash on the ground, where would we be? In your living room! Not holding a door for someone, and not saying "thank you" when someone holds the door open for you. It's good to be the king…if only you were! Talking loudly on your cell phone in public. Cell phone rudeness has been discussed ad nauseum…but apparently, it's just not enougheum. Drivers who don't signal and don't wave a "thanks" when you let them in. I'd call you a pig, but I hate to disparage the little pink critters. Stealing a parking space, taking up two spaces, and/or parking illegally in a handicapped space. Don't even think about getting through the pearly gates. Leaving pee on a public toilet seat. Need I say anything more? Leaving your sweat on the machines at the gym, leaving your stuff all over the dressing room bench. It tells me more about you than I want to know. Adults who ride their bikes on a sidewalk. They invented something special for machines with wheels. It's called a street. Being mean to a waiter, bank teller, or other service person Be kind to people trying to help you, because it's not always their fault. And vice versa: haughty or indifferent service. Be nice and helpful, because it's your job. Line cutters. Those whose sense of entitlement is bigger than their…well, you know. Strollers blocking doorways, aisles, sidewalks. Talk about entitlement. Have baby, will be rude. Parents who let their toddlers run around in a restaurant. They're only cute if they're ours. People who crack their gum. Unless appearing uneducated and low class is important to you. Clipping nails in public. That's why they call it "personal" grooming. Oh, and because it's disgusting. People who ridicule others by making pet peeves lists. As if they've never yelled at a taxi driver for taking the long way when had he not been talking loudly on his phone the whole time he might've paid more attention and then she wouldn't be sitting here behind the garbage truck while the meter is running, as if money grows on trees!
