The job of a PR in Marbella is to approach tourists and entice them into visiting one or more venues - from bars, restaurants & larger clubs. You could be persuasive with your words but it all depends on how good you are at stopping people when walking by! The best professionals can really help make any place crowded though; if that's what gets paid well then go ahead an earn some decent money as well.
