If others at the table will pray, bring their lucky dice, lucky teddybear, wear funny glasses, have unwashed underwear, have glued a dead ant on their forehead or dancing nude while drinking goat milk it is fine with me since I can't see how it will help them. I think they just give me one more out.
If I host the guy with the dirty underwear and the naked dancer has to leave though.
In general I do sort of believe in prayers though.
