The experience of staff.

In the past I was an employee of a large corporation, and have worked with someone who was very unpleasant breath most of the time. Other employees also had to work in very close contact with this employee who did not know he had an oral problem. Of course we all did our best to keep our distance from him as much as possible.
After about two weeks of his employment with us, one of my coworkers went up to him and told him about their oral problem. Of course, the employee felt insulted. Some of us spoke and said: "You have a problem mouth, and it is very unpleasant to work with you." The employee resisted admitting that it had a problem.
To get the situation resolved, the supervisor told colleagues that it was necessary to banish his bad breath, "If you want to keep working here, you'll have to find a solution for him." The reason why the fellow had this problem was simply because I was always eating foods such as onions and garlic. Needless to say, found a solution.
