Scary. Took my kids today. Almost immediately after opening a single homeless man came in wearing gloves and sat next to the emergency exit watching the kids. The front entrance has the hand stamper to discourage child abductors but the emergency exit must be unlocked & accessible in the event of an emergency. It made me really nervous. I alerted management who said the "homeless" guy frequents the place regularly but they won't deny him service because he pays. As our time wore on the man became more agitated walking around the games talking to himself pretending to put in and remove imaginary glasses and sitting down to play a driving game every time a child sat in the adjoining seat. It was pretty clear that he is mentally disturbed and made me extremely anxious. While I'm compassionate toward his circumstances I can't ignore the fact that I had very real concern of his intentions & am worried about Chuck E Cheese's nonchalant attitude toward the matter. We cut our time there short spending both less time & money there. We will not be returning. We'll go to Peter Piper Pizza next time.
