Caller ID shows up as "V2091702540029830100"; clearly meant to obfuscate. They leave no message. I call back after hours using *67 to block my number. I reach their recorded message. There is an option for their Do Not Call List (I avoid this as it can sometimes make the situation worse). The message goes on about their hours and how their patrons are very important to them. The message never indicates who they are or what they represent. Even semi-scummy telemarketers have a message saying who they are. This is a major red flag to me. They go straight to my block list.
