(I'll just add fantasy to everything. It makes life more interesting in general to me.) 

Since the day had been pretty slow so far, Anya spent a lot of her work shift reading books at the counter. Everything seemed to be in order, and she had a good amount of time in between customer visits that day, so why not at least enjoy the quiet? Currently, she was deep in a book about Greek mythology, once again going through stories she had read often when she was younger. There were so many different adaptations, though, and she always seemed to find new important details when she read through them again. 
After a while, though, she started to wonder about the time. The clock on the wall told her that her shift should be over soon, and one of the other workers would be coming to mind the shop for the rest of the afternoon, so she closed her book and looked around one last time to make sure that she hadn't forgotten anything.
