Why do indians talk like that?

[RottingCarrie]

Not their accent but alot of immigrants will repeat words like my dads freind and the guy who owns the place I work at both will ask something and then say "good good good" its always 3 times and I think its mainly like middle aged guys who do it

And they say it like rlly fast and then the rest of the convo is at a normal pace
