My sister used to work in the restaurant industry. She said many of the women who worked as waitresses and barmaids had terrible problems with their fingernails from cutting limes and lemons for garnish. (She was one of them.)
I worked for several years at a small restaurant, pulling duty as a waitress, cook, and dish washer. Eventually, my hands began to burn and itch like crazy and the only thing I could connect it to was the Ivory dish detergent we were using.
