Manners

My usual response to cold calls from banks/insurance companies promoting credit cards or any credit lines is "Sorry I'm not interested, thanks for calling" and hang up.

Today, I received one from Prudential. As I had just finished my very spicy lunch with my lips still burning, reflexively I was too slow to utter the usual line/ hang up. So I let her continue...

Caller: Pls don't hang up, I'm not selling you insurance but to share with you some savings plans

SK: Ok

Caller: Which bank do you save with?

SK: DBS

Caller: Do you know the interest rate?

SK: No

Caller: It's 0.25%

SK:Ok

Caller: Are you currently working?

SK: Yes

Caller: Are you earning more than $1200?

SK: Yes

Caller: Are you a Singaporean?

SK: No

Caller: Ok bye (and hung up immediately)

SK: !!!!?????

Is this a revenge?
