It's pretty obvious from the link in the original post what the differences are between classes and it's not like a car or pickup towing a normal type of trailer is a rare occurence. Too bad they can't either train their employees better or have ones that are capable of doing their job.

Im sure you're also not the only one to complain so blame also has to go up the ladder to management who continues to let it happen when there are complaints. But there's probably someone in there someone who's saying f*&k it, lets keep screwing them..
