I have no problem saying I don't like something and want it to go back. Maybe because I worked in a restaurant for a long time, and it doesn't hurt the waitresses feelings if a dish is incorrect, I can assure you. It might get on the cook's nerves, but oh well. The only thing that ever upset me personally as a server was when people behaved in an elitist manner - i.e. talking down to me, treating me literally as a "servant" that kind of bullshit. And even in those cases, it made me mad, it didn't hurt my feelings.yeah, i'm a fighter too, lol. for me i think it's a Te-Fi thing.
my thoughts about this were mainly from the bad-dish-at-a-restaurant example used (was it in this thread?) at some point. on one hand, i can see someone with high Fe not wanting to upset the group, and thus not complaining about it; on the other hand, i can see them being confident in their social skills and knowing they can send it back with no problem. for a Fi dom/aux, i can see them not wanting to return it because they don't want to hurt the waiter or cook's feelings, though i can see them returning it if it offended them somehow (meat in it when they asked for a vegetarian dish, etc.)
