Ice

Okay let me rant for a minute here.
WHY do people put ice in cold drinks?  Its ridiculous.
I mean, if you put ice in your drink, it's going to melt, and dilute your Dr. Pepper or Coke or Pepsi or whatever.  Same with fruit juices.
It seriously annoys me when they do that in restaurants.  You could be saving so much money just by not using ice cubes!
Let's say there's five ice cubes in an average glass.  That in itself is about a cup of water.  now let's say you get 150 or so customers a day.  Maybe about 125 have a soft drink, and all of them are served a glass of water with ice in it, being 275 altogether.  275 cups of water, for ONE DAY.
For a week, that's 1925.  For a month, that's 8250.  For a year, that's 100375.
Ten thousand three hundred seventy-five cups of water.  That's about  6273 gallons.
... Seriously?
