Every one of us has met a person who made us think, “Did it truly happen?” The basic etiquette is not a difficult thing to understand; nevertheless, there are people who live their lives as if they didn’t know about it, even a little. Be it a colleague, a romantic partner, or just a random person who appeared, these actions could soon turn the whole interaction into an awkward one. I have collected and summarized the signs that indicate the complete lack of manners most frequently mentioned in threads on Quora and Reddit, where people complain about impolite interactions. Identify these behaviors the next time around, and you will be completely aware of the situation.
Talking with Their Mouth Full

If the person opposite you does not mind the making of chewing noise while chatting and at the same time, letting chunks of food go flying everywhere. They do not seem to realize (or care) that it is disgusting, and comprehension of their speech is very difficult.
No Please or Thank You

Everything comes out as a demand: “Give me that coffee,” “Move,” “Hurry up.” The magic words are completely absent, even in small interactions like ordering food or asking for help.
Interrupting Constantly

During the conversation, they interrupt a speaker and barely allow him or her to finish one whole thought. Such a situation makes talking feel like a battle rather than a friendly chat, and they seldom offer an apology for their disruption.
Not Holding Doors or Letting People Pass

People just push doorways and don’t even look back, or they occupy the space as if it were their own. There is no “after you” or taking a side-step, just complete unawareness.
Loud Phone Calls in Public

Unmuted phone conversations have become open speaker conversations for everyone in such public places as cafes, trains, or waiting rooms. The personal volume control? They don’t have it at all.
Eating Other People Food Without Asking

Pushing your plate away and reaching across for fries, tasting someone’s dessert “just to try,” or simply grabbing a handful of goodies from the shared bowl like it was their personal stash. No limitations at all? None!
No Personal Space Awareness

If someone is standing very near in queues, breathing on necks during conversations, or getting very close to another person’s face. They do not seem to be aware of the personal space idea and the invisible bubble that is respected by the majority of people.
Burping or Sneezing Without Covering

Those who are lacking in civic consciousness tend to emit loud burps at the table, sneeze with great force into the open air without using their hands, elbows, or anything else. It’s as if the idea of controlling bodily functions never registered with them at all.
Leaving Messes for Others to Clean

Eating and just walking away, leaving a mess on shared benches, or forgetting to push chairs back at the eatery. They consider that an employee is always there to do their work.
Not Saying Excuse Me When Bumping or Passing

Those individuals who, while moving through a crowd, just push aside cohabitants without saying a word, ‘sorry’ or ‘excuse me.’ To them, the rest of the population seems nothing more than disturbances that are not even worthy of notice.
No Consciousness of Social Signals at All

They continue their conversation even when a person is obviously uneasy, fail to notice yawns or hints of impatience with the clock, and go on unbothered. Perceiving the atmosphere? Definitely not a talent of theirs.
