ただいまですと、15分から20分ほどお待ちいただくかと思います。
ただいまですと、じゅうごふんからにじゅっぷんほどおまちいただくかととあもいます。
Currently, I think you'll have to wait about 15 to 20 minutes.
Gesture & etiquette
Look around at the busy shop, then make a 'waiting' gesture or hold up a finger to indicate asking a question.
Do not try to find a seat yourself. Wait to be guided by staff. Do not block the entrance or other customers.
