Water mugs?

[Quinn]

I use my Nalgene at the gym (Hollah, Mike's Gym!!) and at work throughout the day, when I'm got guzzling mug-fuls of coffee. I've also encouraged my co-workers to bring reusable water bottles in addition to mugs for their coffee, and fill up at the water cooler. I've noticed people picking up on the concept slowly, but surely. It's so much more convenient to fill up a 64oz. Nalgene, rather than an 8oz paper/plastic cup. I know businesses make money off selling bottled water, but I wonder if there's any way to encourage people to use reusable bottles at the gym or elsewhere, in addition to mugs.
