Is it really worth it?

I was getting some groceries at Wal-Mart and almost got beat up. After I had gotten all my groceries I decided to check out the jewelry. When I strolled over with my cart I saw a younger woman screaming at the clerk behind the counter. The clerk was an older lady and I felt so bad for her, it's the day after Christmas and this is probably something she doesn't want to have to deal with. I minded my own business till the younger lady starting to cuss the older lady out. Now I am not one to say anything I usually just hide, but she was getting out of hand. What I did next is something I usually don't do. I told the younger lady "don't talk to people like that" as soon as I finished I though to myself "oh, God Jen why did you say that, you should have just minded your own business." That's when the younger lady turned to me and let me have it. She started yelling at me and telling me to mind my own business and I kind of blocked out the rest, I'm not sure I want to know what she was telling me. During this whole fiasco she was talking to someone on the phone. She told the person she was talking to that she needed to hang up before she got arrested at Wal-Mart. That's when I walked as fast as I could pushing the cart to the picture frames. In fact, I walked around the store for about 20 minutes because I was afraid she was going to come after me. I know I could have taken her, but I didn't want to have to.

I'm not one for confrontation so I am not sure what went through me to stick up for the clerk, but I did. Maybe it's the fact that I don't see how someone could talk to another person like that (especially when the other person looks like your Grandma). I also felt like I couldn't just stand there and not do anything. Even though I didn't stop the mean lady I did keep her from screaming at that poor clerk for just a little while. I actually feel a little guilty for not saying more, but I think it was a good thing I didn't. Was the clerk really being so rude that she had to say all those things? I think that some people need to step back and realize that getting mad over a $10 necklace is just not worth it. The lady needed to realize that she should be lucky that she is even able to buy that necklace. Here is the advise I should have given that mean lady: be happy with what you have, and even if the clerk was being rude, being rude right back isn't going to help. Life is too short to fight over a stupid necklace. If I had a choice of doing it over again, I would in a heart beat.
