What is the proper way to handle this?

Well, I was making that quick run through Wallyworld (aka Wal-Mart) last night to pick up those necessities in life - M & M's being at the top of the list. As I'm going through the pharmacy area for the toothpaste, tampons, shampoo, Tylenol, etc., I find my path blocked by this guy reading the backs of the condom packages. His back is to me and the aisle is totally blocked - and I'm standing there thinking do I interrupt with a "Pardon me" to get past? Maybe it would be better to stand there and tap my foot impatiently and wait for him to realize there are other customers in the store. Then there's the loudly turn my cart around and go to another aisle to get where I need to go option. In the end, I quietly turned the cart, mumbling to myself as I went over one aisle - what is proper etiquette for getting around someone blocking the aisle while buying condoms? Thankfully, I didn't have to read boxes when I got to my destination - feminine products. I can toss that stuff in a buggy and move on without ever stopping to block an aisle. After a co-worker told me the story about having a mini-parent conference on that aisle of Target, I make an especially speedy trip down that aisle - grab and go is the motto. That's definitely one place I never want to be cornered by a parent wanting to know how their child is doing in school. At least the Wallyworld condom man wasn't the parent of any students I know - that would have been the worst!
