Here in Devon, the local phrase from a certain age of woman server is “Hello, my lover”. Catches the odd person out but you’d have to be a dick to kick off about it.
In old fashioned diners in the US the older woman would call you “Honey” frequently. This seems to bother the woke crowd. Me, I like the old school waitresses.
I don’t know for sure, but my guess is that it extended from “Ullo my Love”
There’s also “my 'ansome” from woman to man, and “mah bud / buddy” for man-man.
Like most regional English accents, there’s tons of variations in a small geographic area and many unique words and phrases.
