My boyfriend and I booked a boat tour which he accidentally booked in Chinese so we had no idea what the tour guide was saying (keep this in mind). When we got to the pier the tour guide pointed at a bag of chips and gestured for us to buy them, we thought she just wanted us to try them. To our surprise, the chips were actually for the swarm of seagulls and hawks that were going to follow our boat. One of the coolest (and scariest) thing I did in Japan.
