Towards the end of our meal, we discovered a cigarette butt from the dish of fishes cooked.
Immediately my brother notified the stall attendant (skinny female, long hair tied into a ponytail) and she came over to our table, picked up the cigarette butt, returned to the stall and told the chef on duty about the incident before trashing the cigarette butt. After which she asked my brother ‘你要怎么样’ (what do you want?) and simply sat down at a table in front of the stall.
The chef then came over and spoke to us admitting that it was his responsibility but he has no idea how the cigarette butt ended up in our dish.
