I hate the parking and crowds, the filth, and hoping that some store will have something I want in my size. I can eat better food at home. Shopping in general is a stressful experience for me.
Depending on the mall (Westfield Valley Fair), parking can be so bad for many years now that we avoid the mall completely. While the parking lot can be near capacity (mall is popular), we still avoid it (parking is too hard to find).
