It's not all that different on preload when you're lacking a specific anatomical part between your legs...believe me. I fully expect to hear when I get back from vacation how 18 year old "Johnny" (who's half my age) who makes half of what I do an hour loaded my 6 trucks all week and got done 20 min earlier than I usually do. Yes, I can load faster....but I will not. I will go at my pace, and they can suck it. That is of course, until I see my drivers who will tell me that their loads looked like a piles of amd Johnny had 18 misloads for the week. Blah, blah blah.....fire me...lol.
Don't be picking on me just because I have an extra appendage!
