Any time that you are looking for employment, if you get to the point of an interview, I suggest you promise that you will keep your mouth shut and do your job.
Well, I suspect that just might overdo it just a little. Sometimes talking, such as in sales, requires talking. Nonetheless, there are those who think talking is their job when it isn’t. Indeed, talking may irritate customers and coworkers. Moreover, it can actually reduce productivity. The boss is not paying you to discuss last night’s date or the score of yesterday’s ball game. When it drives up the din in the dining room, it can actually drive customers away. It can become an irritant.
This is especially true when yelling and, or foul language is used. Believe it or not, there are still some of us who prefer a dinner in a restaurant where such language is not common. Even though I spent 9 years in the Marines, I am still irritated by such language.
Finally, when a person who is supposed to be taking orders is talking to a fellow employee or on a cell phone, it prompts people like me to look around. If there is another place across the street, maybe we’ll just go over there. Worse, we might discover we like the other place and never return to your place. It happens.
In summary, there are some places where loudmouths are not appreciated, especially in the workplace.
As a side note, the rest of us should remember that when in a restaurant, we customers really ought not be obnoxious to the other guests. As guests, we are encouraged to carry on conversations, not yelling contests.
