St Petersburg has very few crossings that have traffic light buttons. When there is a button, it usually comes with a huge bright yellow sign with an arrow pointing at it. So for me, when I visit other countries, it's sometimes very non obvious that there is a button in the first place — I'm just not used to them being a thing. So I'd stand there clueless, waiting for the light to change, only to realize a minute later that there might be a button that I have to press.
