I would say the hardest challenge I face has been in my current position with a customer. We had an IRA customer who came in who was very upset, was cursing because her bill was wrong due to some changes not being processed by the corporate side, which is nothing that we could do in our office. So I was able to take the situation from a very unpleasant one, explain thoroughly what was happening, and then at the end I ended up pivoting to another product, which ended up saving her a lot of money, and she was very pleased, and at the end of the day she's a very loyal customer who only comes back for me. So that was something that I had to work through. I was able to clearly explain what happened and kind of tone down the situation, and I was very proud of myself. I think that was a pretty challenging situation with a customer, but I was able to turn it around into a positive experience.
