As an introvert, the last thing I want to do on my lunch time is “network”. Whether I bought lunch, or brought it, I have no desire to spend my precious hour listening to you jaw-jack about your life. You drain the energy from me. Let me recharge in peace and quiet so I can finish up my last four hours without blowing…

I spend the savings on things I really want to do. I spend it on my hobbies, and things that make me bounce out of bed in the morning excited.

Your opinion is your opinion. People who don’t agree are not creepy weirdo’s. You have a very judgmental view on others who differ from you. I assume that’s probably a bigger hold up on career development then bringing lunch to work a few times a week.
