布団の敷き方が分からないのですが、手伝っていただけますか？ — I don't know how to lay out the futon, could you help me? (Ryokan · Stay, Formal — to staff, JLPT N4)

Gesture & etiquette

Point to the futon or the area where it would be laid out, or make a confused motion.

In traditional ryokans, staff usually lay out the futon during dinner. Only ask if it's already late or if it's explicitly a self-service ryokan where futon setup is expected from guests.
