Couple of things.
Those clearly look like bottles which means they have to be quite heavy. One pallet at a time is enough. Dumb***
Second, What in hell was he thinking about using a pallet jack with pallets to lift up the lift gate, then roll it backwards? (the lift gate is attached to the truck) What was that exactly going to accomplish other than creating an accident?
I just had a 25 minute web chat with a business. I had to explain my issue five times and each time he would repeat the issue back to me, then say something that ran directly in the face of what I just told him and that he repeated back to me.
If you're going to hire someone to man your web chat. Maybe you should give them a reading comprehension test before putting them to work.
