Is it Still Service??

So the past couple of days I have been wondering what true service is. My thoughts are that service is something you do for someone that helps them out. I guess growing up in the church (The Church of Jesus Christ of Latter-Day Saints). I was taught that you need to have a good attitude while serving others. While I believe this makes the giver of service happier, and can affect the outcome of the project; I question whether the service is valid if the giver does it grudgingly? I personally do not feel that I have done a service for someone if I complain about it later. If I don't really want to help and then do out of guilt or obligation, I am not receiving the blessings of service. Am I? Though I had hoped to reach a conclusion, I am still confounded.

So I ask you, Is it still service if you don't want to do it?

Does it somehow devalue the charity if you are compelled to serve?

So when I shared my lunch but didn't want to, or when I took my neighbor to the clinic, again after telling her no three times and then giving in to her, was that service? Or was I just being taken advantage of? If your parents make you stay home and watch your younger siblings for free is it service?

I am curious to hear feedback on this one!
