You can very easy use a heavy glitch to avoid the drinking-animations of the character is shown at the pumb.

Go to a pumb.
Wait until you can see "Drink" in the middle of the screen.

Looks like it works for anything that requires selecting an action from context menu. Definetely works for gathering chicken feathers and berries (though after 3 uses the berry-bush becomes "empty"), probably should work for gathering kindling in forest.
