For the first person, such kindness is rare. For someone to sacrifice his time of going to work late to help you is so big act done. For the second person, such is life. There are people who find pleasure in such bad act and will not feel remorseful about it. But now, you know better than him and that's how it mostly turns out.
The act of some people gives us the belief that good people still exist and the first person is from the category.
In the case of the second person, I think I am unlucky in not understanding his trap. I think I was new and somehow trusted him for it as I do not know about it.
