war of ethics at the supermarket

While I was in the supermarket last night at the cashier point, the cashier guy made an offensive supposed-to-be-funny comment to his coworker about two overweight ladies who were approaching him, and sarcastically wishing they go to another line. It really annoyed me, so I said: “they didn’t hear you, but I did. This is a very bad attitude and behaviour. I am a customer just like them, so may be you could at least take your tongue out of your ass (actaully said a near meaning to this in Arabic) and don’t let other customers hear your ugly remarks.” He apologized, and I left. It then occured to me that I intruded and made a comment about him just as he did to those women. May be it was none of my business?
The comment could have been about anyone and not necessarily related to shape. What I am looking for is to know what other people in general regard as an appropriate reaction if the offence is not addressed to you. How positive should one be about it? Let go of it, or attempt to change the world one tiny step at a time? After I talked to the guy I felt I am turning into my father, behaving in a way I used to criticize before. Now I am not very sure!

It's about knitting!

Now that I know I'm so addicted to knitting (I hope this lasts, beacuse I have stashed some considerable stock of yarn), I thought I should have a window to demonestrate my latest pieces. Hence the blog. Sure there will be some personal stuff too, the kind of things that I am not comfortable telling to the closest people around me but I don't mind letting the whole world know about them if it wishes, as long as they don't know who I am :)
