Here are a few alternatives to consider:
Soda & water dispensers in the Cyber cafe - these can serve hundreds of gallons of soda, lemonade, iced tea etc. into our own glasses, mugs and reusable bottles.
Pitchers of iced tea, coffee, lemonade and water kept in a refrigerator and sold by the serving by the folks in Cyber cafe.
I'm sure there are other alternatives to the soda machines we can think of. The point here is that as aspiring religious leaders who may have an eye on exhorting future congregations to greater degrees of Earth Stewardship, we might want to consider putting into faithful action those words that were so enthusiastically received in chapel.
Thanks for all your comments!
