Can you elaborate a bit on what you mean by loose? This is our 3rd Honda with no fuel cap, and they are all consistent. There is an initial metal flap with an indentation, that you push the nozzle through. Then you make sure the nozzle goes into the secondary filler tube behind the flap (you need to carefully push it in at the right angle). I haven't noticed anything feeling loose with this process, are you referring to the metal flap?
I will say to always take great care when inserting the nozzle, and don't try to rush or force it. I have read multiple accounts of folks getting a check engine light, so they bring the car to the dealer, and sure enough there is some part of the capless fuel fill that needs to be replaced because of a broken seal or something along those lines, likely caused by being a little too rough when filling up the tank.
Funny you mention the guy that noticed your passport. Until this past Sunday, the only one I ever saw "in the wild" was the one in our driveway. We went to the local Walmart, and sure enough there was a Passport Touring in the parking lot, so I parked right next to it. We shopped and left and the Touring was still there. Thought it would have been funny if the owner of the Touring had come out before us and saw two of them "in the wild" parked side-by-side!
