Zombies from Spain get a little help

As you well know, zombies have no sense of orientation (we use Google Maps) so most of the times we just wonder around looking like we are lost (actually we are). Also zombies have, let's call it, "needs", so sometimes we resource to hire prostitutes. The question here is to know which female zombie is a prostitute and which one is not.  Hard to tell for a zombie -remember we eat brains...not the same as having brains-.

It just happens that lucky zombies from Lleida (city in Spain) now can easily differentiate prostitutes from non-prostitutes as the city has mandated that all the ones that are "in the business" must wear a fluorescent coloured jacket to make them visible at all times. This is intended to prevent road accidents, although by fluke it is helping zombies to identify them easily. Thanks Lleida!
