Gary put the sandwich back into it's container and ran to the back of the store where he'd not be observed. He then changed into a sedan (cgi cars style) and drove out and behind the mystery machine, at a safe distance for driving while it was raining. His side and back windows were darkened so no one could tell if someone was inside or not. He was glad he had taken those various courses before over the decades, stunt driving, anti terrorism, racing, and other driving courses. He had taken them since they sounded fun and he thought they may be useful in acting gigs he may get.
The rain awoke Wally who got a blanket to share with Droopy who he lay on his lap to share the blanket with.
