Harassed inside shopping center

Why do I have to get harassed by people to donate money, inside a shopping center?<br> I'm talking specifically about the group of people that's setup on the top floor close to game. Every week it's for different cause. I'm glad they are trying to do some good but they are too pushy. Jumping out in front of me and stopping me when I'm just trying to do some shopping. It's come to the point that I have to walk a different route just to miss them.<br>
