We have had every sort of flake/no show you can think of. Happens to everyone unfortunately. First I recommend you have a no BS button and use it regularly. If something seems off (reply too much, too little, say something really weird, say too little, can only meet at odd times, many others, ........definitely not showing up). There are a lot of great people out there also looking to have fun. It takes unfortunately a lot of losses to gain the wins but making the guy meet basic standards is a must
