as far as I know, there is a non-formal rule of three. If someone is refusing three times with the same "degree" of refusal, then they actually don't want it.

as far as I know, there is a non-formal rule of three. If someone is refusing three times with the same "degree" of refusal, then they actually don't want it. There is of course also "Be khoda tarof nemikonam" which is "I swear to god I am not tarofing", after this it is usually acceptable/expected to stop it. Edit: Article also mentions the rule of three > There is an unwritten rule of two or three rounds of offering and refusing in taarof.
