I thought so too, but it turns out he only made about 16.70 an hour. All things considered it was decent enough for a one time thing, but thats really not that much money.
Many people have lots of trouble finding even $10 jobs these days! Plus, those are the people who are most likely to sign up to be TaskRabbits. Furthermore, he can read, sleep, play videogames, etc. while getting paid.
I'd say he got a great deal.
