Drop off and pick up points for uber/bolt users

Drop off and pick up points for Uber customers. So I always use the Puck n Pay entrance when coming to boulders but each time we get there we are told that we must use the entrance by exact to access the mall even for pick ups, why must I be told which entrance to use when if I walk in no one chooses from me which entrance to use. It is very annoying that we get treated this way like we do not bring any money into this center
