My daughter mentioned the same thing. She shopped, dined, went to the movies and all employees were courteous, pleasant and spoke English. Wish it could stay that way...
The Gold Strike Casino where we stayed, was adequately staffed by hard-working, courteous Black and White staff.
They don't need Illegals to do customer service work, as they are apparently paid adequately.
BTW, the employment situation at the Horseshoe and Sheraton Casinos were the same.
They do quite well without Illegals in the Delta area. They keep Americans employed :)
