No Ice, Please
Have you ever removed the lid of your soft drink at McDonald’s and found that it’s filled almost to the top with ice? That wasn’t an accident; the kind folks at McDonald’s are trained to pack as much ice into your cup as possible.
So, to get more drink in your cup instead of ice, which will eventually melt and water down your Coca-Cola (yuck), ask for no ice. The drink will still come out cold from the soda machine, and you’ll have the entire 30 fluid ounces of soda (if you get the large drink size). Alternatively, you can dine in and get as many refills as you like.
