<human>: Can you provide a brief overview of the text?

My husband and I work at an inn, which serves coffee 24/7.  When I started working here, there were three kinds of powdered creamer: original, hazelnut, and vanilla.  How boring can you get?  Part of the 3rd-shifters job is to go to Walmart and buy the groceries needed for the continental breakfast, as well as the coffee supplies.  One day, my husband decided to do an experiment and bought vanilla-caramel flavored creamer.  It was the same price and brand as the other stuff, and the customers loved it.  We had to buy more of it after only a few days!  The customers loved it so much that we decided to try other flavors.  Needless to say, the customers were excited about those, too, so the experiment continued.  We finally had an array of flavors for people to try, the customers were thrilled, and we didn't have to spend any extra money to do it!  

The trouble started when my co-worker returned from being gone for a few weeks.  She hates it when other people make changes to "her" inn and takes it personally when the system is varied in any way.  Guess how she took the creamer change?  It turns out that the only reason we had hazelnut and vanilla flavors was that those were HER favorite flavors.  It was easy to see through, but she still tried to make it look like I was doing something awful.  She said that she knows the customers and that they don't like my "fur-fru drinks."  She also said that I was wasting money by having a variety (even though people use the same amount of creamer in their coffee regardless of how many flavors there are).  Her boyfriend quietly tried to defend her, but it was clear that he wasn't very much on her side.  When I tried to explain that we simply ran out of her flavors and would buy more, she became more angry and scolded me more.  I left that conversation shaking... and it was about coffee creamer.
<bot>: I accidentally replaced my co-worker's favorite flavor of powdered coffee creamer to make way for more exciting and popular flavors.  She reacted like she caught me spitting in the customers' (and her) coffee.
