Shades if grey. Some arenas operate more along the Ferengi model than others. For example, ever been to a coastal resort area in Mexico, and the population density of local attractions and time share hawkers? I found a great idea on a travel board decades ago. Just feign inability to understand and speak to them, and with your companion, in gibberish. Such as the Swedish Chef from the Muppets as one possibility. I guess I should watch that video at some point just to get a better idea of what all is omitted in that snippet. All my formal education predates widespread access to the internet (I used computer punch cards at one point, and still did work via a mainframe into the mid-1990's) and widespread access to even digital still photography much less digital "talkies". But it's difficult for me to get motivated to do so. I just don't think I'd ever get those minutes of my life back.
