I remember that when I was younger I would get asked those questions every time, but not any more.
In the past few years (decade?) there has been a lot of push back against upselling fast food due to obesity concerns. If I had to guess I would say it probably started around when the movie "Super Size Me" was released (2004).
Now, if I order a meal, I might get asked "what size" without any suggestion. Or if I order a sandwich by name, I usually get asked to clarify if I want "the meal or just the sandwich." But I can't remember the last time they actually tried to upsell me.
It wouldn't surprise me in the least if upselling still happened outside of the US.
