Chewing Gum in Office

Chewing gum in Office is something which is an unmanned behavior. It looks very tacky if an employee is chewing a gum and giving presentation or even having a usual talk with his/her Boss. While looking at the chewer "a YAK" feel produce in other persons who looks at him. I am not telling to stop eating gum but it have proper place where you can have it. How it looks if any of our employee is sitting in a meeting with a gum in his mouth, although is don't have to utter a word also during a meeting but yet it gives YAK feel to other employees.

Chewing gum is scientifically good but it has a proper manner, place & time. Smacking a gum also gives an irritation to the other person. While having a gum in your mouth just observe ones, how it perform a strange and terrible sound. I have even observe some candidates too, who appear in an interview with gum in their mouth. Its good that minty gums likely decrease bad smell, but certain things can perform after or before to any important presentation, meeting, conference or interview.

I need you views on this.
