Is AUTHOR wrong in the post ? POST : At work, I microwaved my ham sandwich for lunch. The microwave smelled like pork afterwards. 

Just after I grabbed my food, a coworker walked up and stuck his mug of tea in the microwave. Visibly distraught, he immediately removed the mug, and walked away without microwaving it. 

I feel guilty that I made him uncomfortable, but I also feel like I should get to eat what I want. AITA?
