Very good observation.
Yes, the best food is found in small family run establishments. But many of these well known outlets are slowly disappearing too.
Those foreign workers dominated outlets have certainly brought the standard of our food and beverage sector down to a very pathetic level. China Nationals operating and running zichar and franchised outlets are the worst. The standard is pathetically dismal.
I still can remember back in those days, there was a campaign improve the quality of retail staff. Retail staff had low EQ and didn't know how to talk to customers properly. Now, retail staff can't even speak bloody English so we are back to negative square one.
