Trainer horror stories?

1st Trainer: didn't understand English very well and had a delayed response. Decision was made to get off their truck which resulted in my trainer getting mad and leaving me in the middle of nowhere at a truck stop. 2nd Trainer: wouldn't let me use my card while fueling to acquire shower credits which made me dependent on them for showers. Well, hygiene wasn't a thing for them so no showers unless we ended up at a company terminal. Both his legs and arms were affected by something. They claimed it was a mosquito, but mosquitoes aren't stationary and I had never seen or heard one in the cab. I suspected it was either bed bugs, body lice or scabies. After talking to others, it sounds to them more like scabies. In any event, it started affecting me (first on my hand) and then eventually on my body but I didn't know I was physically affected or when until I was able to take a shower. I told company I wasn't doing team driving because I didn't known what was going on in the truck and I refuse to sleep in his bunk. Trainer told me it was illegal to sleep in the passenger seat and insisted I sleep in his bunk. That was a solid "no" for me. I was told to get off the truck as I had proof and sent in pictures of whatever that was contagious on the truck. Side note: This was not documented by my contact at the company at the time. Trainer lied and said he didn't know I was getting of his truck, when he did. As a result, there's something in my file that states that. I had applied for another position and I was questioned about my second trainer. When I told just this portion, it was like I was giving new information when it was the main reason for my removal. I was denied the position by higher ups. 3rd trainer: A smoker. I'm a non-smoker so this was very hard as I'm also sensitive to smell. Once smoked with the windows up. Would only smoke with the window cracked a little bit and then immediately roll up the window after smoking. Ash tray was on my side so the cigarettes would slowly burn out next to me.
