Kings, lords and owners of all the avenues, sidewalks, streets in Mexico City:
You´ve got to know them:
You can find several, in just one block:
Here’s the first one

And:

Here you can see the same street vendor, with the three trucks (Coca Cola, PepsiCo and Fud) parked in double line, without any care to the traffic jam they cause:

The third Street vendor on the same block, selling their sanitary food to a BBV Bancomer Institution:

IXE BANK has better luck and it is more fortunate: 


it has two street vendors in front of their institution:

But I was missing the other part of the coin:
Then valet-parkings:
In Mexico city, the owners of all kind of business, they don´t care at all to furnish any parking spaces for their customers, providers or employees. So what they do, in complicity with all the local authorities, is to hire (well, really isn´t to hire, because drivers don’t have a fixed income: all the money they get is from tips given by the costumers) drivers that park all the vehicles in front of your car exit, if you have the luck to be their neighbor, 


in double or triple line, over sidewalks, on ridges, producing traffic jams, as you can imagine…

A known American coffee company with their valet-parking:

Another little example:
Not to mention the other guys, that are guys without any job, but they
"work" on the street as:
Street car washers, windshield cleaners
that usually do not ask you permission to "clean" your windshield; fire eaters, guys that use buckets, to take over street parking spaces,
"lending" them to the people who needs it; boys that throw balls to amuse you ( even if you haven´t asked to see them doing that); little girls that put ballons on their bottom
"to amuse" you, etc.
