Pay a stranger's way

I've always wanted to try pay it forward with coffee here in Korea. Not a lot of people are familiar with this concept here, so I was quite afraid of acting it out. Thanks to this initiative, I gave it a try and the experience was amazing! The customer behind me ordered coffee+toast set and I offered to pay his order. He startled at first and then thanked my offer with a smile. It actually felt better than I thought so I am planning to do this more often :)
