Want to see dirty restaurant bathrooms? Go to S.F. Chinatown and eat at the Chinese restaurants the local Chinese eat at.
But that said, at my wife’s work place (assembly), there are various races. Wife says the Chinese/Orientals work the most and talk the least. The Mexicans talk the most and work the least. The Phillipinos get in the most arguments. The whites have the most “I don’t really feel like working” attitude and quit the most frequently and have attitudes of “you can take this job and shove it”.
Pay starts at about 10 and goes to 15.
I lived in the Bay Area for years. Will not eat in Chinese restaurants in SF - no matter what Savage says.
