"Old man, smoking with a cigarette butt that isn't extinguished can lead to trouble if you toss it in the trash bin at home!"
"We know, we know, you told the last guy who got a haircut! We all remember!"
"Good, and the last time? What did I talk about?"
"Talked about... earthquakes, fires, don't take the elevator! Use the stairs!"
Fang Huai beamed with joy, "Eh, that's right! If you remember this knowledge and can tell me three points when you come next Wednesday, I'll treat you to big buns from the shop across the street!"
"Oh, this firefighter lad is really nice! Don't worry, we've all remembered! Next time I come for a haircut, I'll treat you to buns!"
"Right! We can all recite it now, next time we come, give us a few different ones to memorize!"
Fang Huai burst into hearty laughter, holding the clipper up high and shouted, "When you spot a fire or are trapped by a disaster, who do you call?"
The surrounding old men and old ladies chorus together, "119!"
