Hi I was thinking if it'd be a good idea to dynamically price menus. For instance, if our shop appears quieter than usual by a certain time in the day, discount coupons are automatically offered to our fans (online) for use by the end of the day. My brother's a programmer and we're planning to get him to build the system from scratch, but not sure if it'll be worth the effort. What do you guys think? Is it something you guys would find useful?
