Actually, there are two areas in the guidelines that address this:
Under Required Purchase: "Listen for offer to make it “XXXXXX’s Way”. If offered, accept."
In the reporting area, there is a section entitled "Product and XXXXXX's way):
•Order was accurate in terms of toppings, meats, cheeses, bread, size
•Asked if you wanted the sub “ XXXXXX”S WAY”?
•XXXXXX’s Way made in proper order: onions, lettuce, tomatoes, “The XXXXX” ( vinegar 2 rows/oil 3 rows)"
And the report asks: "Did the team members ask if you wanted it “XXXXXX’s Way” and
prepare it correctly?"
That would sort of indicate to me that IF it is offered to me, I must accept. If offered and I accept, I must let them prepare it that way so I can report whether it met standards set by the client.
