Robert..I'm in Connecticut. The clerk had a vague answer about how you ask for a premium ( add...bacon...avacado or double meat). You get a chip when you order and then give to cashier when you pay. Not sure why...the counter is only 8ft long. I think the sandwich maker could tell the cashier. 😀
It looks like quite a few got out...there was only 1 double meat chip left. ( The one I really wanted)
