Rhetoric is a philological discipline that studies the relation of thought to words. The ability to speak, to persuade, to speak in front of the public is important for a businessman. In our university for more than 15 years we have been giving lectures on the discipline "Business Protocol and Etiquette", where we pay great attention to the culture of communication, speech etiquette. We teach students the ability to hold themselves in front of the audience, to enthuse the audience with their speech, we teach them to determine where to start their speech and how to finish it, how to prepare for a speech, the role of facial expressions, gestures, clothing when speaking, telling about the types of speech etiquette. At the end of the course, students anonymously write their feedback on this discipline and let us know that this discipline is in demand by them.
