My clueless coworker: "oh is the cost of living increasing? I hadn't noticed"

Me: "Haven't you noticed the fuel prices going up?"
Clueless: "Oh yeah, those prices have gone up"
Me: "The price of fresh food has been going up as well"
Clueless: "Does that mean takeaway food will be more expensive too"
🙄🤷‍♂️

Lol why do I even bother talking to this idiot?
