Excuse me Kaveh but don’t you return rotten spoiled milk? Erev shabbos for example, I got my milk order and all 4 of the yogurt containers were SOUR. I just picked up the phone and told the driver to kindly pick them up and replace them with good yogurt. He said he’ll be back tommorrow.
Not that I am annoyed. However, its written that if one was to put his hand into his pocket to fetch a particular item or coin and pulled out the wrong item, and has to retry to fetch from the pocket what he orginally wanted, its a kaparah. Any annoyance or seemingly trivial waste of time or money has a purpose. Its a message.
But the point is not that I am annoyed, which I am. THe point is that they cannot sell you garbage. YOu have to do your hishtaldus to correct the situation and call them on it, return THAT MILK! GEt your money back.
