While this may not be the case for all of the dead sea related skin care booths (though I know it accounts for a large chunk of them in my area) - these people often have major quotas to reach in exchange for the room & board and small pocket money they get in exchange. A lot of them are brought to the U.S. with the promise of a job lined up and when they get here they are in a small apartment with 5 or 6 others. Just a slight insight as to why they are often so aggressive in their sales pitches.
