I never really had an issue...but I spent a lot of time in retail, including LP work, so maybe I just know how to blend in better. I was talking with a friend who I got in some mystery shopping and she was "I feel so awkward, i'm taking pictures, they KNOW i'm a shopper" and I was "You send me pictures of stuff you're buying ALL the time, how is this any different???" I've had to half bend back (and i'm like 6'3" with a bouncer build) like I was doing limbo to take a picture of a bottom shelf while IN the check out lane, not a single person paid attention. The world is pretty obvious! :)
