So Much Drama At The Store Today

Yesterday was bananas at work... This morning, I had this one customer who's always been a bit demanding, and she got super mad because there were no bananas. Like, really? Bananas! She went on for like 20 minutes about the lack of yellow goodness in our fruit section. Then I had to deal with some guy who wanted me to change his mind... oh wait, that was last week. Today it was a lady upset because she couldn't find her favorite brand of jam. We had lots of other jams but not exactly what she wanted. So she got mad at me and then at the whole store. At lunch I felt like everyone thought I sucked at my job. But did they really? Am I overreacting or am I just a sensitive person who takes everything too personally?
