Rethink your actions

Recently I was at Target, minding my own business and shopping around. When I was asked by multiple employees of i was finding everything ok, if I needed help finding anything, etc. which I'm not going to lie, most of the time this slightly annoys me and gives me a bit if anxiety. I would just rather mind my own business and shop without being bothered, and if I have a question, I'll ask them myself. About the 3rd employee who talked to me was a young girl with gorgeous long blonde hair..she was stunning. I continued to say "no thank you" to the "need help finding anything?", because truly, I didn't need any help, I was just browsing. 
When I was ready to checkout, I picked the shortest line as anyone would, especially because I needed to be somewhere in a certain amount of time. After waiting for what seemed like forever, I learned that the cash register computer system was down, and they could only accept cash or credit cards. I was planning to use a gift card, but I was willing to pay cash. A man begins to check me out, finally, and though I told him I could pay cash, I realize I left my wallet in the car. I was mad at myself, and was worried I was going to be late to where I needed to be. I told him that I would just be a second and I would need to run out to my car so he set my stuff aside and I went out to my car. Getting back I noticed the lines were even longer but the polite thing to do was to hop back in line, retrieve my stuff and be checked out like everyone else. I probably waited in line for five more minutes, and then the young girl that spoke to me earlier in my shopping trip pulled me out of the line and said she could read me up at the photo center. I was shocked. I thought to myself "why would she choose me out of anyone else to pull out of line? I did only have three small items but still." 
I thanked her many times and continued on with my day. As I was walking out to my car, I realized that I was not necessarily rude to her when she asked me if I needed help shopping, but I could've been a little more friendly or appreciative. I realized that I shouldn't just blow people off because I want to be left alone while shopping. She was just doing her job and more importantly, she was trying to be helpful. 
One of my favorite quotes is from Ellen DeGeneres, and she says it at the end of her show every day, "be kind to one another". I admire this quote because it needs to be done more often. There's so much rudeness and inconsideration in the world.. Sometimes the best thing to do is to just put a smile on someone's face and move on with your day. 
After this day I tell myself that I won't let something like this happen again. I hope my story teaches you a lesson as well, and next time you are shopping you think of my experience.
