Indeed, although this is not a problem I have to contend with, other than politely refusing suggestions. By the way the rubrics for the traditional liturgies have “Stomen Kalos!” Proclaimed at specific times; I have never actually seen a liturgical service book with instructions on what to do with a disruptive person or hooligan, but most churches have ushers, Anglicans also traditionally have fearsome dudes called Vergers, so called because they carry a formidable mace or staff called a verge, although their function is primarily ceremonial and concerns timing processions, and the ancient church had an ordained order called Doorkeeper; Doorkeepers were one rank above Exorcist, which was actually the lowest, or technically according to Christ the highest, rank, in the early Church, since the bishop is required to be servant of all and least among the ministers, a requirement in practice ignored by many infamously poor shepherds and wolfs in sheeps clothing, one of the earliest being Paul of Samosata, who is also as far as I can tell the world’s first Unitarian.
