That is pretty clever. Reminds me of the “angel shot” that one would ask for at the bar.

I mean, insofar that you’re using a code, it’s “clever”, but the point about the angel shots are they aren’t actually real, so when someone’s orders one, the bartender knows.

Having the code be “H&M” is like having the code in the bar be “could I have a beer please”.

Gonna get a lot of false positives.
