Dollar General complaint: Haughty clerk

When I entered the store this evening, I was not greeted by the happy, smiling face I’m used to seeing in there. As a matter of fact, I received no greeting at all. There has been a significant rearrangement in the store, and I had to ask the clerk, Katrina, where the card aisle was. She pointed me in the right direction, and I made my selections. Upon returning to the front of the store to check out, the first register, I walked up to was self check, and the clerk was standing behind me. She informed me I didn’t have to do self check, and I told her I preferred not to. I then jokingly made the comment that I wasn’t paid to do her job and I didn’t want to take her job away from her, to which she replied “oh, you couldn’t do my job”. I again replied jokingly “you don’t have a clue”. Rather hatefully, she replied “oh, you don’t have a clue”. As I was walking away from the counter to exit the building, I asked about a previous employee who had worked there for several years, and Katrina stated she didn’t know who I was talking about. I told her that she had worked there for several years. She then informed me that everyone was new. I’ve been commented that she had always been so nice to me to which Katrina very haughtily replied “oh, I’ve heard some horrible things about her”. At that point, I left. I believe she could use some coaching about her attitude. I will probably be shopping at one of the other locations in the future even though they aren’t as conveniently located.
