In my country there is a unique job, although I’m not sure if that activity can be called “job”, anyway it is called “franelero” which means someone who carries a cloth. So when people are looking for a place to park their car in busy and public areas the guy called “franelero” guides you by shaking the cloth to a place where you can park, after parking you have to pay him for guiding you and for watching your car while you’re doing your stuff (eating in a restaurant, doctor appointment, etc) Some people (me included) prefer to pay them because they are afraid of them (meaning if you don’t pay them they can damage your car) I believe this is just a sort of Mexican mafia but too many people make a living as a “franeleros”
