"When the Son of Man returns, the world will be like the people were in Noah's day.
In those days before the flood, the people enjoyed banquets and parties and weddings right up to the time Noah entered his boat and the flood came to destroy them all."
"And the world will be as it was in the days of Lot. People went about their daily business -- eating and drinking, buying and selling, farming and building --
until the morning Lot left Sodom. Then fire and burning sulfur rained down from heaven and destroyed them all.
Yes, it will be 'business as usual' right up to the hour when the Son of Man returns.
References for Luke 17:30
