Imagine a hotel with a doorman at the front door. When you want to enter the hotel you tell the doorman your name and nothing else, and he will go with you to your room. You don’t see any other rooms, only yours. You don’t know your own room number. The doorman will go with every guest to their dedicated room. You only know the name of the hotel and nothing else.

The doorman can also quickly give you another room because the room that was actually your room has water damage.

The doorman will also check that you don’t carry anything illegal and will not let you in if you do.

The doorman will also check your ethnicity or race and only let certain ethnicities and races in.
