I am looking for words analogous to ‘to greet’ and ‘greeter’, to use about people as they depart. I may say:
Claire stands at the entrance and greets people as they arrive. She is a greeter.
I want to say:
Sam stands at the exit and ??? people as they leave. He is a ???.
I have found the word ‘valediction’, which is defined as ‘the action of saying farewell’, but I cannot find anything that means ‘the person who performs valediction’. There does not seem to be a verb ‘to valedict’.
What words (verb and analogous noun) best describe Sam’s role?
