I have a Cineplex evening-night-out which is good for 2 movie admissions as well as a popcorn and two soft drinks. I want o use it to treat my friend for her birthday. She's good with the popcorn and drink but I no longer drink pop. I know from previous experience that with this type of deal they will only allow drinks from the fountain so I can't request juice or anything. The only two options I can think of are either asking if they'd just fill the cup with tap water or offering the free drink to someone else in line. Thoughts?
