It is good to stand up for others.
Joe is eating lunch at a cafe when he sees two customers berating a waitress, Linda for their food not being salty enough.
Joe wants to say interject into their argument and say something.
Joe says that the two other customers need to lay off and calm down as it's the chef that made it, not the waitress.
Joe says that he agrees with the other two customers, that the food is indeed unseasoned and bland.
Linda is relieved that someone is on her side and that Joe pointed out the most obvious defense on her behalf.
Linda is shaken up as she's being accosted by multiple customers at the same time for something she can't control.
