Loading and Unloading hassles

I went to places that pretty much called me a sissy for not being able to push a 3000 lb pallet uphill to their forklift. They get someone to help me do it, then start barking orders, like "back in the day we used to just whip those things around", even when his boss told him to come help he stayed on the forklift. These guys are likely no more than 10 years older than me. Felt like saying having gone that much downhill, ur likely going to die in another 10 yrs" but i didnt, as long as its done u get paid for unload where i work- MOMONEYMOMONEY
