Whats up with solicitors in the malls here? They are relentless!

I used to experience one or two growing up in the 90s, but when I moved to Houston a few years ago I noticed that these people will shove a coupon or cologne sample in your face. On the way back they do the same thing! When I tell them, you already came up to me, go away, they reply back 'third time will be the charm'. I can't go to the mall without like 5 or 6 of these people all up in my grill. It just seems like such an archaic practice to get people to sample to buy things. In 2024, why are we still doing this? Does anyone buy anything from these guys? People must, I suppose or they wouldn't still be annoying. Also, not like race matters, but you never see white people doing this, its always middle eastern or something. Is it a cultural hustle? Ok, rant over.
