If you want to have a little fun, ask the store personnel to open it for you after you purchase something.
A few months ago I bought an extra SD card on the way to a family event so I could use it in my camera since I forgot to bring the laptop and had nowhere to d/l the pictures. After I got my receipt I asked the cashier to open the package for me. He said he couldn't do that. So I went to the customer service/pickup desk and asked the woman there. She said she couldn't do it either. I asked her to call a manager. The manager listened to my explanation (I needed the thing opened now and did not have scissors), looked at my receipt, and told the CS woman to cut it open for me.
Of course, she was completely paranoid about something happening so she worked at a snail's pace. She was sure there was a trick involved somewhere but at least it wasn't me who got a cut finger that time.
I think I'll do that in the future because maybe if enough people do that they'll change their packaging to something a little less hazardous.
