Trainings are a wholy different cup of tea. I do highly technical trainings, that people pay a lot [1] to attend, and sometimes I really can't help some participants. No, you can't run docker containers on your phone. Laptop is required, it was on the website and stated in the email you received two weeks ago. Or: No you see "file not found" means you need to run this command from another directory. Yes, you type "cd" to go there. No, the script won't work without Python installed, we covered this on a slide two hours ago. Wait how did you solve the last four exercises which used Python too? Oh, this is a work computer and you don't have admin rights to install anything? Right, your admin is sleeping now because of timezone differences. Uhh let's try to find a portable installer.

Meanwhile, the second half of the room finished everything, and that one guy way ahead works though an exercise I didn't even cover so far. But I just smile and try to help, because I'm a professional.

(sorry for venting)
