I suggest that Tom's concern is valid, the absence of security personnel, and astoundingly their own admission that they have no contingency for coverage during shift change. (Good time to hang around the cashier cage with a gun, huh?) And do they all 'change shifts' at the same time? Perhaps the real problem was shortage of staff which they don't want to admit to customers. And though Tom hasn't received a response yet, I'm betting his reports will get some attention. I've reported things on post-stay surveys. Sometimes I get an apologetic email with promise to "elevate this to the appropriate department", sometimes nothing. The place might also have a shortage of overall customer service staff to reply to complaints.
The issue is security in the property, an element normally included on post-stay surveys. In my many casino hotel visits in Vegas and other cities over the years I've seldom if ever experienced hard core panhandling inside any of them. Certainly never had any "demand" money. Occasionally have had a stranger "congratulate" me for a jackpot or good hit,and then hang around chatting me up in a friendly way which I figure they are hoping I would have a generous impulse to share some wealth. I just ignore them and they go away. But very infrequently does this happen either.
As for the "right" to panhandle inside any place, most businesses would rather not have it happening as it can sour customers, whether they have Kevin's heart for the homeless or not.
I once had a guy, seemingly intoxicated, going around in the casino asking players if they would order a drink for him (asking in a friendly way, BTW, not persisting when the player declined). He had apparently already been warned about it at least once. I don't know if someone reported him again but several security guys magically appeared. They treated him very politely, "Hey, buddy" etc., then had him turn and stand in a certain spot where his photo could be taken by the eye in the sky camera, said "good job man" then again in a friendly manner walked him out the door, talking in "buddy buddy" tone the whole way. Perfect way to handle such a situation, the panhandler didn't get upset and start a ruckus, etc. Maybe if he kept coming back and begging for drinks they might escalate action against him. I really don't know but it would be reasonable to do so IMO. But I digress.
