Earlier quoted context omitted.
Most of the time, they don’t ask for money explicitly at all but they will put procedural roadblocks so one pick up the cue and bribe them. Like Priority Shipping for a bad analogy. Pay to fasten and smoothen your experience kind of thing. Of course it’s illegal.
Same for me registering a car. The dealer sent me 12 documents and the inspector wanted a few more. The dealer wasn't clear what they were. So I had to waste a few hours for two days. The agent was able to cut the queue and I spent as much time as to expose the engine number under the bonnet. The agent is the funnel for bribe from me to the department.
There is now plausible deniability because the agents look like they are actually providing a valuable service.
