Yes they do. My pet peeve is being in a checkout line and Mom is trying to control her screeching little “angel” with, “Johnny, you need to stop that. Thank you.” Needless to say, the screeching continues.
Even parents who discipline their children would be reluctant to do so “in the checkout line”, mostly because some busybody “liberal” would report them to CPS.
However, if you discipline at home, you don’t have many “checkout line” incidents.
