I definetly saw an abundance of Taiwanese employees this past Friday and Saturday. The RideOps did a pretty good job, but they couldn't understand the guests when there was a problem, and that could be a major safety issue.
I also witnessed another Taiwanese employee working a register who could not figure out how much change to give. The guest in front of me in line needed to tell him exactly what to give him, quarters, dimes, etc.
My only concern is with the placement of these employees. Any employee who will be dealing with guest safety or interacting directly with guests at all should be able to converse with them. I fault the management for some of these decisions. For instance, the employee that had a hard time at the register, had an American woman getting the food. Those employees should have been switched.
