I had the vilest experience today with a mailman from Janesville on N. Palm Street.  He was screaming at me that my stamp was used (my neighbors heard him).  Of course the stamp was never use but i cut it out of an envelop that was never mailed and taped it on the one to be mailed.  I explained that I done this before and never had a problem as the stam was clearly never used he basically accused me of lying!! Realising that he must be a nutcase I asked him for the envelop back thinking I will take it to the post office myself, but the nutcase ignored me and kept on walking..i run after him in the knee deep snow in my slippers while all the while he was ignoring me calling him and asking for my envelop back.  When i finally caught up with him out of breath and asked for the 12th time for my envelop back he yelled in my face that he has "no time for the likes of me" and that I wasnt "worth his time".  Wow! Janesville you can be so dam vile and evil!  I think what he meant by the likes of me was my europpean strong accent!!  wake up and smell the immigration Janesville..THIS IS AMERICA ..you loony own!


You do understand that one mailman doesn't represent the entire city of Janesville, do you not? The actions of one person do not justify you calling the entire city "vile and evil". On another note, you should have gotten his name and reported him to his supervisor/boss. It would've been far more productive than running after him in slippers, if your story is indeed true and not made up in an attempt to make the city look bad.

he should not have yelled like that, but there are many times when I have received mail and the stamp was not cancelled. I did not then cut it off and tape it to an outgoing envelope.... I don't know that you are allowed to Scotch tape a stamp on an envelope like that...Sorry.
