Would you eat at a restaurant if the mashgiach goes to strip clubs (I know a few of these as does @ExGingi I bet )
Huh?
Unlike quite a few around here, I don't know that you know me personally. I definitely don't know you, other than your DDF persona. Why in the world would you think that I know anyone, let alone a mashgiach, that goes to strip clubs?
FTR, I agree that seeing how a person acts in Shul and davens might be an indication of their Yiras Shomaim. I can tell you with almost absolute certainty that the owner of Judaica World would not talk during davening, definitely not during Kadish, and I'm pretty sure that the same hold true for his son-in-law (even before his recently assumed position of 11 months community service).
