We have items that are specific to one size of sandwich that we offer, however, people can choose something other than what is required/allowed. For example, any sandwich can be made into a salad or a wrap but only the regular size sandwich. People right now can choose small or large even though they should only be selecting regular. This also happens with gluten free bread choices when it should only be regular or large and people select small but pay for regular or large gluten free bread.
