Why do people do this at jobs?

So do you guys have that person at your job who they will ask you to do the simplest stuff they could do themselves?

"Can you do me this? Can you get me this?"

It's honestly annoying cause at first you think they actually need help but they're just too lazy to do it themselves. Why do people do this? I'm genuinely curious why in their head they're so comfortable with using people.
