I hate when coworkers ask "what's for lunch today?"

I'm not sure if it's just me but my lunch breaks are my time to gather my thoughts and have moments of peace with whatever food I decide to eat for the day.. Every now and then there is nothing wrong with eating lunch with a coworker but let's not make a habit of it! This will stress me out because you're not sure what you want and I have no time to sit and wait for you to decide... It honestly drives me nuts!! Usually when it's time for my lunch break I just run outside to avoid everyone and any possibility of someone asking me this question. You have to protect your peace at any means necessary.

Do y'all find this annoying? If so how do you handle it?
