It can vary from a smiling TSAer who knows that it is all a joke and does a quick examination of the bag, a quick wanding and you are on your way...

Or all the way to the TSA person yelling with veins bulging in hos neck in full command presence pose forcing you to wait until two LEOS can be present. Each LEO will have his hand on his gun just in case... The will turn each dirty sock in your carry on inside out and go through each pill in your prescription bottles.

And anywhere in between.
