He said that part of it is business in that if people cannot order and make their wishes known, it slows down the lines (which are continuous).
He also said, and I'm paraphrasing: "Press one for English; 2 for Spanish. Why are we giving preferential treatment to just one other language, Spanish.

In college in the late 1960s, my university gave in to demands for a special room in the Student Union for African-Americans. We had perhaps 50, maybe 100 on campus - the football team and some others - out of about 6000 enrollment.
It was controversial at the time, so we all got bent out of shape and started asking for our own rooms at the Union. Mine was for "left-handed Indians" (that would be Native Americans now), but I was turned down, being a party of one.
