I worked in a small warehouse the summer before I got my degree. It was just the manager, me, and the delivery driver. We sold air conditioning units. Small ones you could move on a dolly and big ones that went on roofs of businesses. I had to move those with a fork lift with no previous experience. I would get the forks within a couple inches of the unit, get off, see if the forks were at the right height, change the spacing of the forks, etc. Sometimes I'd have to repeat the process 2 or 3 times before I was satisfied. Then I'd get back on and creep forward until I could pick it up. My boss would crack up with how slow I was. Thankfully we typically just had to load 4 or 5 large orders in the morning, then the rest of the day was spent putting up incoming inventory where speed didn't matter.
