IMHO, just because he visited the store shouldn't be a concern in whether this is a legit case. I say this because I recently had some surgery, and after a few weeks of recovery, I couldn't wait to visit my local home center. It's my "happy place" and whether I'm buying anything or not, it's therapeutic for me when I visit there. Who can say if he wasn't just window-shopping (either figuratively or literally... ahr, ahr, ahr!!).
True enough.... The big box I used to work for would allow the senior citizens center nearby to bring their residents over before opening to window-shop and or walk around for exercise. So, your point is well taken.
