When I held a party or picnic, I used to fill a cooler with cans of soda pop and ice to keep them cold. But at the end of the event, I found I was usually going around and picking up a bunch of opened cans that still had liquid in them. Sometimes, I’d swear someone had opened a can, taken a single sip and abandoned the beverage. Each ounce of pop I poured down the drain was money out of my pocket.
So I started buying 2-liter bottles instead of cans. The bottles were cheaper, but presented a couple new problems to be solved.
First, the end of the night would come and I’d realize that I had three or four open bottles of the same kind of pop like Coke and it would go flat before I had a chance to drink it all myself. So I started putting out only one or maybe two bottles at a time. I’d keep the others chilling in the fridge, to be pulled out as the earlier bottles were emptied.
Second problem was that instead of partially full cans at the end of the night, I’d find partially full cups of pop that people had poured from the bottles. My solution to that was to buy smaller cups. Instead of 12-, 16- or 18-ounce cups, I look for 6- or 8-ounce ones.
My guests are welcome to fill the smaller cups as many times as they like from the 2-liter bottles and I find myself tossing out less soda when the picnic or party is done, which means less money wasted for me.
