I live alone and yes, I do chug. But I keep a second jug for guests.

I don't believe that for a minute. Situation: You have chugged all of your own milk, and only the guest milk remains... at the moment, no guests are present.

In such a case guests will have the choice of pop, water or taking their chances. Once I chug the milk becomes mine.
