One very rude and unprofessional guide

My complaint is specifically directed at a particular employee/guide, Nathi. He started the tour by refusing to introduce himself and instead insisted his name was “Nobody”. In the first five minutes he had made several snide and rude personal remarks, including “are you deaf” and “your clothing is super gay”. Nathi’s obnoxious, rude and disrespectful manner towards clients is extremely unprofessional - We paid for a service and expected Nathi to be courteous and professional at all times. His bad attitude detracts from a fun experience. All the other guides, Joe and Rector, were extremely friendly and courteous. It is unfortunate for one unprofessional person to ruin an experience and damage the name of a business.
