I once had a TL driver sit in his truck for about 15minutes while backed into the only loading door at a company.
I saw him doing his paperwork and talking on the phone so I assumed he was getting loaded. When he was done with his paperwork he started up his truck and drove away.
This genius blocked the door for over 15 minutes while other trucks waited. I guess it was too much effort for him to pull to the side and let someone else back in.
