AITAH for not catering to lactose intolerant friend?

My friends and I got together this weekend since the weather was nice, and we had a little cookout. I was the griller so I chose what was done to the meats and I happened to put cheese on all the burgers. My friend saw this and goes “you know I can’t eat cheese right?” I had forgotten so I apologized and put some other meat on the grill for him but he said he wanted a burger. We argued about what to do and he said that he wanted me to go to the store to get more burgers. I refused and he then sat away from me the rest of the cookout and didn’t eat anything else. AITAH?
