Cold callers in Spain are rubbish. When they can be bothered to call, about once a month, and when I can be bothered to pick up the phone, almost never,  they often ask who might they be speaking to. Today a charity rang and the guy refused to say why he was calling but aggressively persisted in finding out who I was. He was undeterred when I told him he was speaking to the owner of the brothel, probably didn't want me to think he wasn't indulgent, but still insisted on a name. I told him I was Adolfa Bonifacia Ecolastica Homobona Buenaventura and hung up. You have been warned time wasters.
