It would be my luck that the greeter will be a CHL as well and offer me a map to the ammo, nachos, etc.
I can hear it now, "Gee, sir, we're really glad you are here. We don't get many guys alone in here, wearing untucked shirts eating nachos and buying ammo unless they are on their inaugural Wally Walk! Most guys are walking in here about three steps behind their wives, grumbling about wanting to be somewhere else

!"
Being currently umemployed, perhaps I can work at Walmart as a greeter in the evenings and on weekends. Play a little game with myself to "spot the Wally Walker!" Perhaps even offer certificates of completion, suitable for framing!
We'll have to develop some signal, though, just in case the concealment it too good to spot. Some codeword to use when greeted. How about something like this...
Greeter: "Welcome to Walmart! How are you today?"
CHL Wally Walker: "Doing fine, thanks! Just have a ache on my hip. Can you tell me where the ammo is?"
