LOL. I was just going to ask about these, too! They say "no employee interaction," but staff in these places don't always have name tags or a desk plate. So if you have to get the name, you have to interact.
And I agree that the size of these places makes it really difficult to take 11 photos unobtrusively! It's not like it's Lenscrafters or Walmart eyeglass facilities. The only way I could think of to do this shop would be to say you're shopping for frames and need to take some photos of what you like to look at them at home to narrow your selection down. At least if you have to capture specific things, you can pretend you're taking pictures of lenses.
Around here, it's not like there are usually several people in the office at once, where you might be able to slip in, take pictures, and get out without anyone taking a lot of notice.
I learn something new every day, but not everyday!
I've learned to never trust spell-check or my phone's auto-fill feature.
