That morning had been hectic. By the time I boarded, I was already feeling shaky, a clear sign my blood sugar was falling. I reached for my protein bar, but the woman sitting next to me quickly asked me not to eat. She said her young son, sitting nearby, had “sensitivities” and would get upset if he saw or smelled food. Wanting to avoid conflict, I reluctantly put the bar away and decided to wait for the snack cart.
