Sorry, if that has been asked elsewhere and I just could not find it, but is there any chance to disable Change Price Button? I suppose in many cases only Restaurant Manager should decide about prices (Actually I think it should be more general case than having a fish restaurant, what I understood as the reason for change-price-button to be introduced. In case of fish restaurant itcompletely makes sense to me, but already in similar scenarios where you sell products dependent on weight, for example, it would be better solution to connect a weight to pos-system, to get price by that). I also agree with emres view of general pattern, I for example was playing howto best configure pizzas, and it appears little more intuitiv to me, showing an add extra ingredient button, where we now have stuff like, void, gift, change price...
