I agree, sometimes we over think things. We can be more suspicious looking by just not acting normal.
I used to worry about waiting near a counter for my meal; it's normal. Taking 20 minutes to eat; it's normal. Asking questions, it's normal. Taking pictures of products on shelves; it's normal (they assume you are scanning the barcode to check pricing ). Asking the same question I asked the same person two months ago; they don't remember me, it's normal....
