How gullible is the "average" person?

Good pay isn't it - the current lorry adverts say £51k.
It's not that great if you read the advert closely.
Starting salary of £40k but, work 5 on 3 off, including Saturday and Sundays. Start times from 3pm onwards. Bonus of £1000 to £2000 if you work all your weekends.

Good pay but there are sacrifices.
