I think he's a moron.

Anyway, does a casino have the right to ask someone to leave who is blatantly advertising for a competing business? If someone from the horseshoe went into the mirage poker room with a big wearable billboard promoting the shoe I'm sure legally they could be asked to leave.

Same thing here, the auction is a contract so they have proof that it's paid business advertising and would probably have the right to escort the guy off the property.
