They don’t need the money.
I’ve never tipped a cow or even tried. It’s mean. Imagine snoozing on your feet and suddenly having someone push you over. Crash, smashed head, maybe a broken rib.
Fortunately, I don’t sleep standing up and neither do cows. They lay down and take short naps. They are always aware of their surroundings, even when snoozing, so it’s hard to sneak up on them.
They weigh over 1000 pounds and are well balanced on their four legs making it hard to simply push them over. Imagine trying to push over a small car.
Plus you may not know that cow you are attempting to push may actually be a bull. Bulls don’t take any shit.
