If you made this meme from the UK, you should know... the cars don't actually have to stop for us, unless we are already out on the crossing. So if someone stops to allow us to cross, a thumbs up is a good way to acknowledge them being considerate.

A staggering number of drivers don't seem to understand this rule though, the amount of times I've had to dash back off the crossing because someone decided they can't stop for 5 seconds is way higher than it should be!
