The counter staff didn't dare to hesitate. He took the cash out in a hurry and placed it in the bag designated by the robbers. In this case, no one would joke with their own lives, even if the leaders blamed them, they couldn't care much.
The robbers put the bag with the money in their hands and did not check whether there was still money left in the counter. They began to withdraw from the bank in an orderly fashion. Finally, the macho man who had the submachine gun retreated. Before leaving, he quickly used the automatic gun to write two large English letters, "S.B." on the bank's wall, and then quickly disappeared from the doorway.
The whole process took less than five minutes. Although someone had reported to the police, the police might not arrive within five minutes.
