Hello! I am a English Speaking tour guide. Tomorrow, I will attend a customer (probably American lady) for 1 hour of excursion of an area in Kyoto, Japan after more than 2 years of absence of tour guiding due to pandemic. During the excursion, I will have to take pictures of the client and send it to the travel agency along with a tour report (how the reactions of the guests and places of visits were like etc...). As the picture is supposed to be used for the PR of the company (the excursion is advertised on "trip advisor"), I will have to explain it to the customer. In case she doesn't agree with that I can just mention it on the report to the company and don't need to send the picture. I am concerned about the way to ask her that before we built some good relationship in such a short excursion and privacy matter means a lot. I will have to ask her to drop a line on the review on the trip advisor site after the tour, too. What I thought of is.... (after greeting and explaining about the itinerary) "our travel agency asked me to send a feedback of this tour along with some pictures of customers. As the pictures might be used for their public relations, if you mind it, you could tell me. Then I can just report them about it without your picture or I could take pictures of you in the unidentified way like,,,, from back side or hiding your face. How would it be better?" Would these phrases and timing serve to make myself understood without hurt the happy feeling of the customer? Thank you in advance.
