Few episodes back Tina flipped when Shiv referred to her a “Dear”! Had me grinning as it’s what annoys me too. In India many people refer to strangers and randomly call someone “Dear”. “Dear listen” “Dear no you can’t do this” “Dear please do this”
While it may not be exactly a rude thing to do but yes it sounds very stupid to call people you don’t find “Dear” as Dear” ! So dear is reserved for people you are genuinely fond of and very close to. Not thrown around casually! 😊
P.S - I support Tina in throwing a hissy fit over “Dear” from someone who is not a friend and certainly not Dear to her. 🤪
