I was out shopping this afternoon. When I got home I noticed that the receipt from a discount clothing store included a 20 oz. soda that I did not purchase. I called the store and talked with a young lady that answered the phone and the store manager to resolve the situation. Since I was in the store en-femme, I decided to use my feminine voice on the phone. I was pleasantly surprised to be addressed as ma'am twice during the phone call. The store carries men's and women's clothes but since the majority of the customers are women, the store employees may have been more inclined to assume that they were talking to a woman. However, I'll take any confirmation that my feminine voice works that I can get. Being called "ma'am" on the phone almost feels better than being called "ma'am" in person.
