I have a Rubbermaid drink bottle thingy. I carried it around at Frolicon all weekend, usually filled with rum and Coke.
Today at work I took the cup to the drinking fountain to fill it with water. I unscrewed the cap and it REEKED of rum. Anyone within 20 feet of me must have thought I was a total drunk.
I don't drink in the office... it just smells like I do.
