A human being, if he wants to gain the respect of others, must, first of all, deserve others to do it.  If not, it is just a mad dog that likes to bite people and still wants to demand the respect of others.

There are many old people, demanding the respect of young people, but the manners are not equal to an animal. Who doesn't like talking to a polite person? Respect for the elderly and respect for children is very common, but this only happens to people who have a heart. If you put yourself in a situation where you were polite in your words but still bitten by an old dog, how would you handle it?

For example, if you go to a grocery store to buy something and say - Are there soft drinks and a cake? What's happening?

There's nothing wrong with that, but the point is you're talking to a tough old lady, no matter how polite you are, she'll curse you. Since you lack the subject in the question, you should use the question: does the owner have soft drinks and pastries here? Perhaps the owner of the grocery store wants to hear that.

But the problem is that even if the sentence lacks the subject element, it is still a meaningful question for the buyer to use for his or her needs.

In this regard, it could be either because you lack the ability to express yourself or you have encountered a mad dog. A goofy dog ​​who likes to be the mother of the world and has nonsense concerns with others.

Should there be a subject in the sentence? Of course, a full sentence always has the ingredients needed to make a sentence meaningful. But if it doesn't, it's still enough for a human to understand. It is necessary to be polite to an unfamiliar person, but it is not worth it if it is an old dog who loves to teach life and swears at its customers while they are not offended.

Overestimating yourself is also stupid if you're not qualified to prove yourself. On the other hand, showing yourself as a city person and looking down on people from elsewhere is another way of showing yourself as uneducated.
