I drove a stick for about 5 years. I still kept stomping the floor with my left foot for about a month after I switched to an automatic.
I do that when I drive the wife’s rig. Except about half the time I stomp on the brake - haven’t caused a wreck yet, but I won’t be surprised. It’s interesting to consider the subtlety one uses when applying the brake - tap/tap/slowly depress - and then compare that action to the clutch - quickly shove all the way to the floor. When the clutch action is applied to the brake, hilarity ensues...
