I spent 1 hour of unpaid work experience for a telephone provider. I found out on the day that I would be handing out pamphlets in a supermarket.
The person who was supposed to be helping and/or supervising just gave me the pamphlets and walked off to chat with his girlfriend. The only time he intervened was to tell me off for answering a potential customer’s question. I knew the answer, but I was supposed to defer to him (not that he told me beforehand) so that he could sugar coat (read - lie about) the answer.
I never went back, and tell all my friends to avoid that company. I’ve since discovered that they also do many illegal things to get more money from their customers, but will suddenly comply if you know your rights so that they never get caught.
The might be a little too much personally identifying information if I mention them. I don’t want to risk it.
