The sprinkie guy will look at it but he'll be a bit clueless about the "is it OK" and since cooking lines are always shifting around coverage areas will change. An added bonus is that when the fat fryer does arrive, and it will, we like our fried goodies, just look out the window at passerby's, nobody will think to do anything about it. At least if it's chemical there's a fifty-fifty chance that the IT&M guy will remember or have have pictures of the line configuration from last time and bring it to somebody's attention. These guys are always on the look-out for new work and reconfiguring the system to meet the new line set-up is easy money.
