"I suspect the delay is because they just want to keep you huddled here, in front of the screen, ineffectual. If there's no contact by about ten o'clock you go about your business as usual. Make a bit of show about going to the office."
Two guys are waiting for kidnappers' contact, but nothing happened. So one of the guys tells the other to go to office and "make a bit of show."
Not so sure what does this mean, please help~
