What is up with this?

Today I took three of my kids to the mall which is a very brave thing for me...or crazy? I go to the mall about three times a year at this point, if that. I enjoyed their enjoyment and it was definitely worth it but why are people getting right in our faces now and trying to sell us stuff from their booths??? Why are the malls allowing this? This is so annoying. I had to tell the same people at least three times NO. Why can't any of them speak English clearly either?
