That is very unfortunate. You can talk to someone and request an apology for the tour guide’s rudeness, but everyone experiences things differently, and it is ultimately up to the travel agency that hired the tour guide whether or not you will get an apology. It would be difficult to get a legal apology. First, go to the travel agency that organized the tour package and tell them what specifically about the guide’s attitude was rude, and ask them to do something about it.
