My new 4 screen theatre(which opens Friday) has a unique set of combos.
I am using 6 core items- popcorn,soda,candy,slush,nachos,pretzels and I have 2 sizes of items- small & large,
3 combos sizes- small, large and family. And it then is a mix and match idea.
Small combo has a choice of any 3 small core items. Large combo is choice of 4 large core items. Family is 3 small and 3 large choices.
RTS software tech support has been great in helping work out the programming bugs. They said they'd never tried it this way.
I'll report in a few weeks how it's being received by patrons.
