Do you catch more flies with vinegar or honey?

I am very familiar with the expression "you catch more flies with honey than you do vinegar" But also the expression "the squeaky wheel gets the oil" or squeaky wheel gets fixed" so the one that is the loudest or makes the complaint gets the attention. While I think both are true I do feel you do not have to be mean to get results you can "squeak" in a polite way showing common courtesy, and get results. 16 yrs ago the company I worked for closed over 300 people unemployed, however there was a problem the company never filed our unemployment so there was a bit hassle with getting things pushed through proving we did in fact work and pay our UE taxes, so were therefore entitled to our claims. While many people were often disgruntled annoyed, angry and naturally upset over this [all goverment offices work at a pace of slower to slowest to begin with and this made it worse] When I went to apply etc, I smiled, stayed calm and pleasant, explained the situation etc, and while I did wait the extra time that first day, because I had been nice enough and friendly when I had to return to the office and again get in the LONG line to wait out the day again, the woman saw me in line, and called me in to one of the back offices, where she helped me out and so instead of staying there for hours 3 seemed to be the least amount of time some spent much longer, I was in and out in less than an hour that second day. So yes being nice does help. On the other hand, there were times when I stayed nice, I stayed calm, but some people will only repeat a pre packaged line, that is meaningless and in my case not at all applicable to the situation, at that time I did become some what indignate, but under the circumstances most would agree with me, however it also worked in my favor, I was loud enough drew enough attention that someone saw me and came over and helped. You see my mother had just had surgery and the hospital lost her. According to the hospital despite the fact that I had just spoken to 2 staff personal who told me where I could go to see my mother I was being told I could NOT go to that location because it seems my own mother was a figment of my imagination. Needless to say after the FIFTH person I spoke with gave me more of a runaround I was rather upset that they LOST my mother after her surgery. So sometimes yes you do have to use the vinegar, however the person who saw me so upset who did come to try to help and in fact DID help to her I was very nice and polite still very angry and upset with the hospital and others but I did not take it out on the one person who was trying to help me. So over all yes I do feel you will get more help by being nice but every so often you will encounter those who mistake your being polite to mean they can walk all over you and dismiss you, in those instances vinegar is better than honey.
