Judgemental coworker

Yaro, i had a rice bowl yesterday for lunch. It was rice with chicken curry. It was a lot so i left half of it in the box and put it in my office fridge. I reheated it for lunch and had the rest today. My coworker saw me, made a grossed out face and went "didn't you eat that yesterday?" I said "yea, it was left so i reheated it". To which she replied with disgust saying "basi khana kyun khare". I tried to explain to her that I'm broke and can't waste food + it's not like it's spoilt, it's just a day old. And she couldn't wrap her head around it. It took me completely off guard. Has anybody met any weirdos like this?
