Last time this happened to me was my first visit to a Turkish barber. After the third what I was scared of appearing racist because he had such a strong accent, so I just said “aye pal” and gave him a thumbs up hoping that would be the end of it. Then suddenly he had a ball of fire on a stick waving it at my head.

Turns out he was offering me an ear-flame which id never heard of before. Its pretty terrifying with no warning.
