Automatic Phone Call

On 3 separate occasions at 2 different casinos, when I was down more than $2,500 in one session, the pit boss made what it sounded like an autmoatic routine phone calls and dictated my name on the phone and seemed to be sort of filling some informations. On one of these occasions, the pit boss actually politely asked for my social security number. There was no associated heat at all. Does anyone of the experts know what is this routine. I appreciate the response
