In Mexico it's blatant and it's everywhere. In Europe most people would never think of bribing a police man to escape a fine while in Mexico a mordida is business as usual. There are police men whose only job is to get money from all the people they stop.
Here's an anecdote from my early years in Mexico. You have to check your car once or twice ever year to get like a govt sticker otherwise the car cannot be used in some places. Well sometimes the queues to do this process are extremely long. I've seen first hand someone from the verification center going to every car in the queue and asking "with jump or without jump?". Meaning, if you want to jump in front of the queue you have to "pay extra".
All of this shouldn't be a surprise.
