AITAH for eating lunch while a nurse was stuck with me?

I get monthly infusions that last around 6-7 hours. Recently we swapped to doing them at home, so the day looks like this nurse arrives, starts the IV, starts the infusion then sits on the other couch on her phone / computer til the infusion is done (there is some risk of reaction so I have to have nurse supervision). The last two times I've just skipped lunch since I didn't want to be rude having lunch while she's sitting there hungry, wearing her mask for the entirety of the infusion (I don't wear one since it's my home and if I've got something then it's all through the air). Today, I asked my gf to bring home barbecue on her way back from the dentist and I couldn't help bur feeling like I was being rude having lunch while the poor nurse was stuck with me until the infusion finished. AITAH for not skipping lunch?
