I would say most people do not expect God to set a bush ablaze and speak verbally to them, but make it obvious they should do this or that thing.
Of course, one would hope that a pastor would realize feeling called to scam money from his congregation to renovate his house and buy a car to come from Satan, not God. But temptation is strong. :P
That's why many conservative evangelicals did mock and accuse charismatic tv preachers of being grifters, unrepresentive and false teachers. Though that public tension and conflict seems to be abandoned for the sake of political unity nowadays.
I've known calvinistic missionaries (all dead now) from these groups, they speak of being burdened, and "feeling" called, but they're clear that a personal burden is not a revelation or prophecy, it's just a personal conviction from the text combined with circumstances and an affinity of where to go, not the voice of god. No different than a person feeling convicted to become vegetarian because of something they read. They cited some passages from paul about going where "he choose" (I've no interest in looking that passage up at this point) and the use of casting of lots to show it's internally driven conviction and pragmatism and not a revelatory special calling. Being explicit that anyone hearing the voice of God probably needed medical help, personal prophecy wasn't a source of inspiration and truth but were warned against.
It's been a big part of the modernistic bent of the dominant Calvinistic protestant denominations. It was also drove the focus on literacy and certainly influenced the trend towards academic and textual rigor.
Widely abandoned in the U.S. only quite recently by low and high protestant calvanistic conservative groups alike.
Pentecostal and charismatic groups have been around obviously but weren't taken too seriously and were even warned against by dominant evangelicalism, but that has relatively recently changed in conservative Presbyterian circles and influential groups in baptist circles like Sovereign Grace Churches (though they aren't baptist, they've become heavily culturally entwined via southern seminary and other places).
This has basically reintroduced miracles and promoted an embrace of magical thinking in laity's daily life that was long absent from those bookish, stuffy, severe, and practical protestants.
