Good post, though I do not think things are hard for the immigration officers, yes they are also police officers. They just make up their own rules to suit themselves, every IO is different, they won't lose out on anything.
The normal police officers are different, they have lost a lot of their bungs from the bars, clubs and other businesses because they were closed during the pandemic, so as far as what I have been reading, they are trying to compensate for this now by putting the screw on if you know what I mean.
