I know it didn't really come across in the post, but I didn't take the cashier's comments too seriously. In all honesty, I found the whole conversation rather humorous especially given the other items I was purchasing. I wish I could play it off as looking too young, but considering that she had to check my ID for the alcohol purchase I do not think that was the case.
One thing that does irritate me are anonymous comments. I do not mind opinions that differ from my own. In fact, I think both responses made good points. I just wish people were brave enough to attach their name to their thoughts. I have NEVER posted an anonymous comment to a blog. If something is worth saying then I had better be willing to stand by my opinion.
