Warning! Gypsies ahead!
These ladies set up shop right in front of the local cathedral; as soon as wary and unwary folks wandered across their paths and sightlines, the gypsies were onto them like bears on honey. Something like that anyway. Wave them off as they approach you, say no no no in your language or Spanish, whichever occurs to you first, because you don't want or need their cheesy mantillas today. Or ever.
