For how early it was, he was very attentive to their surroundings. Sherlock watched outside the window, and as they drew closer to their destination, he seemed to be looking for something in particular.

"Here! Stop here!" he shouted to the cabbie, who was briefly alarmed before pulling over. Sherlock jumped out, tossing a bill at the driver blindly. "He's here, John! There's his truck!"

Pulled to the side of the restaurant, there was indeed a white, blocky truck. No one would think twice about it being there, and about a man carrying produce and meat inside. Brilliant. But going off the schedule was his flaw. While it might've fooled the police to go a day early, it wouldn't fool Sherlock Holmes. The man had to know they were onto him, so he jumped ahead a step. After this, Sherlock was sure his movements would become more sporadic. This was their last chance to have the upper hand.
