Annoyed on NYE countdown

NYE countdown is happening and it ticks 12am, here is my boyfriend stuffing is face with his food until he finished, while I was standing and waiting. He then got up his mouth smells of Salmon trying to kiss me. I said this is not how I wanted it to go, I was so pissed off, it's not like he didn't eat a whole 3 course dinner! We were supposed to go do fireworks and I told him he can continue eating his plate, because I don't feel like it. He say my annoyance. Is this petty of me?
