Careless food service?

Two incidents that seem to show WDW food service is getting careless... At a counter service restaurant, cheese was put on a dish when the menu never mentioned cheese.  The dish was replaced.  Another incident was potentially more serious.  Some bleu cheese was found at the bottom of a steak salad.  Again, no mention of cheese on the menu.  It was determined from a very helpful waiter that the cook had cheese from another salad on his gloves while preparing the steak salad.  The problem is that the other salad also had nuts in it.  Someone with a nut allergy could unknowingly eat something that should never have nuts.  Let's hope this doesn't become more frequent.
