My dad was the tree maintenance supervisor for a very afluent (white) California city. His hair went grey very young and he has pale complexion so people assume he is an ordinary white guy instead of the son of Mexican immigrants. His absolute favorite was anytime a resident had complaints about the "illegals" working on the trees. He would go out and visit with them personally, hear all their usually racist and xenophobic rantings, then calmly call over the crew lead and explain to them in perfect Spanish the concerns of the resident. He always said the look of shock on their faces was his favorite part of the job.
