I understand that I would ไหว้ someone older than I am. I understand that a person working in the service industry (a restaurant server) would ไหว้ me. What is the situation with a restaurant server who is my elder? Which status takes precedence?
(It's specifically a situation I was thinking of when exchanging "สวัสดี" with an employee of a Thai restaurant in the U.S., but would the same rules apply in Thailand? I suspect I would not ไหว้, but that feels slightly funny when greeting someone older than I am, so I wanted to check.)
