Question

Hi Ally, Happy teachers day! I really appreciate your all effort to have a pleasant class all the time. I can't say thank you enough. And I have a question on what I recored during the meeting with the tissue supplier. I don't want to be offensive but I'm coughing and runny nose. Would it be OK ((if) we didn't have) lunch together? In this sentence, I could not figure out exactly what he said even though I played recorded ((if) we didn't have)part a dozens of time. The Korean American translated it into Korean "He said to skip the lunch because of coughing and etc." Can you guess what words he spoke? Thank you.
