I generally give my real occupation, freelance writer/photographer, especially on shops where I have to give my real name. I do it for two reasons. First, it makes it easier for me to talk about it, should the salesperson so desire [and it happens quite a bit, especially on car shops where that's an open invite to show off the room in the trunk]. Second is a more pecuniary interest, the possibility of obtaining work in the future.
As far as friends go...well a small handful [3] know what I do because they get a free meal occasionally. One is a retired chef and boy do those FD meals get dissected on the way home. When he comes with me on a shop, I do a second recording on the way home because we end up talking about the flavor profiles of the meal and I never know when a gem will come out that will fit the report perfectly. The rest basically know I only write and shoot.
