Slightly related but not, it seems to me it would be easier on the servers if they filled up my cup with maybe only 4 or 5 ice cubes instead of the 10-15 that they usually do. If you gave me more soda in my cup initially, perhaps you wouldn't have to come back 3 more times to bring me a refill??
I'm sure there's science behind it, but _____ science.
whenever I go to a theme park, or the movies, or anywhere and have to but soda, I always say "No Ice Please"
and I realize, you can even see, the press the button and the cup gets filled like 60%, a little bit more than half, and since I Said no ice, they have to press the button a second time and manually fill it up until is full,
plus the soda already comes out cold, you are paying for 60% soda, and a bunch of Ice that doesn't even melt when you are done with your meal, it takes like 40% of the whole cup
sometimes they look at me like crap, but, I don't do it to be cheap but because my teeth get sensitive with the ice, and then I realized how much ice they do fill it up with.
as far as restaurants filling up, they should just give you a glass jar of soda for you to fill up yourself, that simple
