My uncle went to sau paulo the other week along with 4 other representatives of jcb, they were over their to speak with a company jcb was hoping to land a contract with which in the end was succesful, anyway they were put up in a swanky hotel and everything seemed fine until the 2nd night, my uncle was getting ready to go and see a concert and had a knock on his hotel door, he answered it and standing their was some mad man with a machete, he went to attack my uncle and after a breif struggle my uncle managed to trap this lunatics arm in the door and proceded to slam the door on his arm until the man gave up and made a run for it, my uncle who was badly shaken phoned reception and told them what had happend and to his surprise reception did not seem alarmed or shocked and casualy sent someone up to see what had gone on, apparantly this happens all the time and tourists and holiday makers are targeted a lot by the crazy locals, I'm sure its not always like that but just a word of warning, my uncle could not rest or settle for the rest of his stay especially at night when he was in bed, crazy!!
