Bad response to a thank you?

It's not the words, so much as the WAY it's said and who it's coming from. Sometimes due to our pride, we don't like to hear things like that, because it makes us feel needy or incompetent. We shouldn't though. Everyone gets a helping hand now and then. But actually, if that response was said in a kind way, it sounds nice. It entails that the person realizes they may do a lot for you, but it's no problem. They *enjoy* doing it and making you happy because they feel as if you are worthy of the favor. Just smile and give your appreciation to the host so that their blessings will continue. And don't forget to return the favor (if you already do, then great)! But never let the person go feeling unappreciated; they may not be there the next time you really need them. If you feel like your nose is constantly rubbed into it, or they always act as if you owe them your life, politely steer yourself away from them and their assistance in the future.

That depends on what the context was of the "thank you". If it's sarcasm and the person says thank you and you say that then yes it adds fuel to the fire. If it was in a positive context than it's fine.

How is that a bad responce? That isn't a bad response at all. All that means is that you deserve what ever it is that person has done for you and that you are thanking them for. Don't obsess about small things like that.. and don't worry its not a negative thing to say at all, if anything is accually possitive. Gl,

Depends if it was said with a sarcastic tone or not.

my friend says something like that, just check the tone and the smirk on the face. if it seemed like a joke it was ment to be harmless, otherwise the guy is a dick

All depends on the tone

Not if you are telling a girl "thank you," right after sex.

I don't think it's negative, but it does depend on the tone in which it is said.

It depends on the tone in which it was said. If it was sarcastic trying to say that's all you deserve or that you deserve something bad that they gave you, then you might be justified to be miffed. If it was said nicely, then what I think they were trying to say is essentially, "No thanks is necessary." In that case, it would be ungrateful and overly sensitive for you to be miffed.
