Yes, certainly. I'll heat it up for you. Is this spoon okay? (Implies showing a standard spoon)
Gesture & etiquette
Hand over the bento. Mime eating with a spoon if phrase isn't understood.
Do not try to use the microwave yourself. Do not forget to ask for chopsticks/fork/spoon if needed, as they might not be given automatically for all items.
