Firm Prices!

Does it bother anyone else that restaurants will make a dish with meat without the meat but won't change the price?! For example...I am at a local restaurant with a amazing sounding mac and cheese (except for the meat of course) they said they can take out any of the ingredients. This made me happy until  I was told I would still be change $13.49 even though I was not getting the bacon or the chicken! Ridiculous (at least I think so)!!! Anyone else agree?!?!
