I spend most of the time in my lab and do my work. I prepare food for myself everyday and want to eat it in the lab when hungry.
I generally prepare limited food only for me and hence I want to eat alone without sharing. It is okay for me to share my food once in a month (or once in a long period) but not every day. Since I eat food daily in the lab and don't offer it to my friends/labmates, I can sense that they are developing an unfriendly opinion towards me.
In India, it is minimum courtesy to offer the food to the surrounding people (who are not eating like me) before eating. Since the other labmates only eat their own food occasionally in the labs, it's not a big issue for them to share their food.
If I offer food then I end up with either much less or no food and I can't spend my time and money on preparing more food so that I can have sufficient food after sharing also.
How can I send positive vibes to labmates without sharing my food?
