I did the DtD thing for about a week. That company – “Global”, IIRC – was scammy. They did their recruiting via placing “management trainee” ads in the newspaper and told us new employees that the encyclopedia sales was something new they were trying out.
First time working a neighborhood on my own, I came across a family which already had a set and one of the company’s crappy plastic banks – from 20 years prior. I wasn’t about to continue working for a company that lies to its employees, spent the rest of the night sitting in a playground swing set, and didn’t bother showing up for the next outing.
