I have to disagree, the employee who refused to sign was not authorized to sign for this particular package. The driver went to that location and no one was there. He just has to go to the rear delivery location to seek a signature. After 3 attempts at that location should he RTS package. Each one of those locations is a separate stop and should be treated as such. If no one was at the pharmacy and he tried to deliver to the front desk and they refused would you send it back
Wrong you don't Ni1 or Cl1 a package for a business that is open just because someone would sign for one package but not another.
Pharmacies at grocery stores are open everyday and hour of are delivery window for them so that theory isn't going to work.
