I tried an experiment. About two weeks before Spider-Man 3 came out, I changed the names on my soda's. My 12oz is now a child's size, my 20oz is now a small, the 32oz is a medium, and my 44oz is the large. As soon as my 20oz cups are gone, I am changing to 16oz for the small size and have the 16oz currently on display.
It caused a little confusion at first for both the customers and the employees, but I think the timing was good--lots of customers and lots of concession sales since the change.
The first two weeks we pointed out the difference. Now we just fill the orders. I don't have the exact numbers, but I have noticed a marked decrease in sales of child sized soda's, except for the ones that went into the kid's packs.
I do have a question, though. Did I do the right thing? Yes, my goal was to get 50 cents extra from each sale. But does 50 cents cover the added cost of the product, the cup (the large cup cost is significantly more), the disposal of that bigger cup, the clean-up of that larger spill in the auditorium, and on the large-- the refill? Many more people are buying the 44oz. and we are seeing many more people coming back for that refill. (Could just be that PIRATES is just a long movie.)
Anyway, your thoughts?
