Carls Jr.

So last Wed. my sister and I went to Carls Jr. for lunch and had this crazy experience that has been eating away at me since.
We were there right at lunch time 11:45 or so. Order our lunch and let the kids play in the play place. In the middle of our lunch my sister says, there was a man that crawled up in the play place and I haven't seen him come down yet. I get up a few minutes later and look from the ground up, every where is pretty visible to the eye except the highest level by one of the slides. So I tell her I don't see him, but there is a part I can't see. We figure we don't hear him and maybe he went up and got his kid and came down. Usually that is what happens to me. Well, a few minutes later we hear a mans voice coming from the top of the slide. My sister yells for her daughter to come down and we ask her if a man is up there. She said, "yes, but I didn't go by him." We have her stay down with us. Well this man comes down the slide a few minutes later and adjusts his shirt then goes to the bathroom.
Well, I can't stop thinking about this because I didn't say anything to anyone even though I had the feeling to do so. Even if I were to tell the other children's parents, but I kept telling myself I didn't see him do anything wrong. Today I go into Carls Jr. and tell them and they have me go back to the computer and look at the cameras and show them who the man is. I do so and everything plays out just as I tell you the story, except before he goes up he grabs some napkins put them in his pocket first.
The police are coming in and may want me to come see them tomorrow. Crazy huh. I wish I would have said something though.
