Free Samples
When I was 14 years old, I went to Seoul for a Tae Kwon Do tournament. We had some time to walk around the city, and at one point, this guy working at a food stand stuck out a long metal pole at us and started shouting, “ICE CREAM!”
Seeing that we were tourists, he was offering us a free sample, but it freaked us out a bit. Later that year, I bought a book from a second-hand book sale in Luxembourg. That same guy was in it. Story credit: Reddit / MrLuxarina
