I got that Eta, but you should see these sales techniques; it is amazing how they finagle a yes out of a no.

If people knew how to say no, if they were stronger, if the uneducated knew their rights more, if there weren't too many elderly who were easily taken advantage of, if there weren't too many desperate people...

There are too many ifs to excuse the techniques used by shifty sales people and not enough laws to protect those people they take advantage of. You can't blame a gullible person for being gullible, but you can certainly blame somebody for taking advantage of them.
