Oooohhhhh, I just had a flash of what he might have meant by sandwich...there's a "thing" in Las Vegas where you try to bribe a FDA into giving you usually a room upgrade....so you put a $20 or a $50 or a $100 "sandwiched" between your credit card and driver license...hey sure, give it a try to get the resort fee waived. Let us know how it goes.
Unless he really meant "here's a bologna sandwich".
