Everyone's had this happen to them. A customer will want a refill on an iced tea lemonade. And as far as I know, almost all stores will refuse to do iced tea lemonade refills mainly because of the limited amount of lemonade in stock/shipping costs. There were many a summer day last year without a single drop of lemonade. A lot of business lost even as we had PTL photos all over the store.
How do you charge for an iced tea lemonade refill but factor in the lemonade? Because I've been telling customers that I can only give them the iced tea portion for the refill price.
