A smart(Stupid) thief

I am not sure whether should i say he is smart or naive...i have one guest from one of the well known listed insurance company check in to my hotel 2 days back...unfortunely one of them become a thief...or i shouldn't say thief cos i think he do not want to take but he saw that the handphone is at the chair near lobby and he think no one saw so he just took it....but then he did not know that CCTV is looking at him and when we found out, we got no other choice to call to his company...poor him....since we brought up to the HR department who made the booking and after the manager have view back the CCTV....according to them, they will take action to him...actually after we saw the phone he took...we feel that is not worth at all for him to take the phone....the phone looks like this:-

Do you think is worth to take this phone and will get sack from the job?? Let me know....
