Taco Bell — employees

There is a manager at the grove oklahoma store. He is missing teeth, and often has blood shot eyes. He and his coworkers were openly discussing drug use in the store. Not only me, but my son as well, heard their discussion. I do not appreciate my son being exposed to drugs at a family restaurant. When i brought this up to others in the community, they told me that they have seen this same manager smoking marijuana in the dinning area or parking lot late at night with other employees. It is obvious that he is under the influence of something. I do not understand how an employee can get away with this. I have only witnessed it in the late night or evening shifts.
