My folks weren't spankers, although mom used to threaten us with the dreaded Craftsman yardstick occassionaly ;-) Usually "the look" was enough to get us to settle down.
I do remember one time I was being a brat in church, and my dad took me to the back of the church to get me calmed down. That didn't work, and he gave me a swat on the thigh (I was wearing shorts) The swat made a huge sound that echoed through the church, and everyone turned around to look at us. I, of course, played it up, sobbing and carrying on. Bernhardt couldn't have done it better, LOL.
After that, when I misbehaved in church, I would get taken to the car.
