Grocery shopping a deux

Tomorrow the Chief & I are going grocery shopping together.  This will be interesting; this has been primarily his purview since he retired over 6 years ago, though I retained primary responsibility for drawing up the grocery list.  He has proposed dividing the list, taking opposite sides of the commissary, so we can get outta there that much sooner.  All well and good, but I suspect he'll finish first, being more familiar with the commissary's layout.  I'm not really worried, though; we came to an understanding about packing suitcases, we'll work this one out too. :)
