Is ıt really all about positive signal sent to Universe?

Hi there,
It is the question I have kept  asking myself,
''is it really all about  sending positive signals to unıverse and waiting to be returned to you  in the same way?''I have been also trying to practice, it sometimes works sometimes NOT,
















Let me give you some examples,
The other day I called a taxi statıon to order a taxi, I was told  that they were sending one, a driver called me in 5mıns saying that he is in 5mıns away, it was mega quick! of course I got delayed apprx 10 mın sınce I was not expectıng to have one that quick, during 10 mın. the driver called me twice,

Finally I was there with the driver and apologizing  for the delay and sending positive signals!, however he was very tough on me and being rude, I felt that positive signals are not working, so I decided to reply hım in the same way he treated me - sayıng that if there was a  traffic I was  to be the one waiting for him, why then he was reacting  so harsh... ,as soon as I  said this he stopped moaning!?
Do you think that people understand only the rudeness, if you take the blame on yourself they try to be more rude??

Another one,
My TV satellite was to be connected and I have kept chasing the guys sınce 3 wks,
In the first case, I checked with the maintenance if ı should buy any specific receiver , they said '' there is nothing specific, ı could buy any brand I wish'' so I did buy one and came home ,
The technician came and could not connect anything and he told me that the brand I bought was not working in my building?!?!?!
I took a deep breath and sent positive signals to universe, I went back to the moll with a lot of hussle ın the snow and returned the receiver, the specific brand the technician gave me was not sold in that specific moll, so I went to another onet etc.
Finally I got the right brand  and got another appointment with the technician,
He came but TV is not working yet:-(( the reason was not apparently the brand of the receiver! it was related to the out cables of the apartment!
I was there again sending the positive signals to the universe and hoping that it will be replied and TV was goıng to work by a mıracle.
The technıcıan could not fix the cables that nıght and after that night he dıd not come back until the weekend!
And finally today in the mornıng time I woke up and directly called the maintenance and kindly asked if they can fix it today - the technıcan came and fıxed it...
3 wks being patient, not loosing my temper but also spending  a lot of time and energy as I told you above but not getting nervous about it..
Now I realize that the signals does not finalise anything but helps you not to get angry, in other words accept people's failures and be the one  patient all the time...

What do you think? I really want to hear your comments, Am I interpreting the signals in a wrong way?
thanks
