Why is there a charge for shredding chicken on top of the regular price at the Aberdeen taco Bell? I think $1.30 extra is robery please respond.

No, this item is posted as shredded chicken taco for $1.89 then the clerk charged him $1.30 extra for each taco ,then when he paid he didn't get shredded chicken they substitute chunk chicken for shredded

Because you are ordering off menu. Most taco bells are individually owned franchises. The owner of that location has set the prices accordingly.
