diners at eating house

I had my late dinner at this place near to my house. When I was doing the sketch, the cleaner who was a Chinese national and other food stall helpers stopped work and talked among themselves about my sketch. The food stall helpers went back to work soon after but the cleaner just stood next to me and watched. The drink stall helper came and asked him to continue to work and to leave me alone. I was grateful for that. The photos depicted that it was too late for a picture of the family in my sketch and the man sat down at the same table soon after the family left.
