There is nothing quite like the combo of cold ice cream and cold water. Every time I ate a ice cream as a kid, I always craved cold water, but never wondered why. Apparently there is some science to this, and I learned this when I visited my first authentic Italian gelato shop, where a glass of cold water was brought to the table after I finished my ice cream, a very nice touch.
I love your little diy office, you've made good use of a small space.
