Like I know it's not so common on the US but here if you pop across to France for a week you get ads for everything in French. Despite my best* efforts I still speak abysmal French. You're not going to sell me shit in French (or indeed anything anyway).
I literally just crossed a border, I didn't become French, please.
This despite me being pretty lazy and generally letting my data get slurped left, right and center.
Perfect market efficiency strikes again...
