A young gentleman was patiently waiting behind me while I was deciding on a drink until I noticed him. Offered him to go first but reversed offered for me to go instead. After I made my purchase, I was finding where to wait and stand in this small store. He stood up and tried to offer the only seat, I kindly declined. He was so polite. I wasn't too sure his age, if he was in his 20s. Hopefully we meet again.
