We are using Aloha 6.7 and operations wants to start charging a deposit when someone orders a Moscow Mule to cover if they steal the mug. Does anybody have any creative solutions on how to set this up? We were trying to avoid using a comp or promo to get rid of the deposit. I could do a negative value item but that seems potentially risky and something we would have to keep a close eye on. Curious if anybody has any recommendations. I feel as if I am missing something easy.
