The first time i was called uncle was by a young malay chap who was working in Baskin Robins. I was 29. I was cool with it, he was being polite.

The first time i was called uncle by an older person, this case an aunty, was when I was 38 and buying stuff in the wet market.

The first time I was called uncle by an even older person was last month, when my neighbour who's a grandma wished me good morning uncle.

Ah...time flies by so fast. I rather reminisce on times gone by TS then fret about being called and unker.

when u r doing a sales , then ur customer call "Sir, harga itu berapa ya ?" ...i will feel like, u want to buy for me ?

I use Sir even when I'm the customer. Just being polite.

Wait until they call you ah pek.
