For some time now, I’ve noticed a pattern of address term usage in local restaurants and cafes (three of them): I am addressed by servers and other employees there as boss. The speakers are all Hispanic men, younger than me (I’ve never gotten boss from anyone else; I don’t have employees of my own); and of course it’s crucial that I’m male; and it might be relevant that I’m a regular customer in all three places; and it might be relevant that the atmosphere of all three places is informal. (Some of these men sometimes address me as Arnold, but other times as boss.)
I assume that this is a resolution of a puzzle in social relations: sir would be the standard address term in service contexts, but seems far too formal and distancing given the social situation in these three places; and Arnold might seem too intimate on some occasions; so what to use instead?
What I don’t know is where boss (said with a friendly, even jocular tone) comes from. And why just Hispanic men? (Non-Hispanic and female servers seem always to opt for first names in such places; if they don’t know them already, they find them out and then memorize them.)
(Address terms are a long-standing interest of mine. Discussion of pal and sport here, boy here, and medical address terms here.)
