Last week, I went to the McDonald’s near my office in downtown Boston to grab some lunch. Like I always do at fast food places, I ordered some food and a (free) water. The clerk asked me if I meant bottled water, to which I replied “tap water is fine.” His response? “Oh wow, you’re brave.” I did end up drinking the water, but very uneasily. I’m not dead yet so it can’t be that bad.
