Why do restaurants put statements like "specials cannot be altered due to preparation" on their menus? The business is about customer service. If someone doesn't want the sauce, how hard is it not to ladel it on at the end? I get that some items are tough to change, so make that point to a customer who asks for a special/altered preparation.
Seems like restaurants are annoyed by the requests and are trying to eliminate them. It turns me off and I almost never ask for them to change anything so this isn't me complaining about the reaction I get.
