A man was sitting next to the napkins and utensils area picking the skin off his fresh tattoo and was tossing the skin every where. I asked staff to call airport security and they refused. I talked to the "skin" man and he just continued to pick his skin. After the man left, I advised staff that they clean up the utensil area, and two of the staff proceeded to take a break. Still dirty and disgusting. No one should go here! Staff to immature and do not care about health standards!!
