I try to stay covert, even though the guidelines pretty much require us to take pictures out in the open. My main reason for being sneaky is I don't want to waste time explaining myself to employees. With a long route, an extra few minutes on each shop can add up. I do my outside inspection before I go in the store, and already have a list of photos I will need. When I finish my purchase, I snap my pics and drive off within a couple of minutes in most cases
But I agree with your husband, lol. Doing it on the sly can be stressful. When I have a route of mixed reveal / non-reveal, I look forward the the reveal shops as a chance to relax.
