I'm that old?

I'm that old? I keep wondering sometimes. Maybe they just want to be polite. I don't know. Even though by looking differences in our age, he/she should call me "Adik". Getting more and more confuse. I was on my way back to my house. It's happen at Maybank at Alamesra. Someone said: "Broadband bang.." Quite shock because the man was older than me. *Blank* for awhile. 

Food court usually using "Abang" "Kakak"

It's keeps happen went we were eating at food court. Any food court, I think. Crowded. Also, fighting for costumer. Sometimes bad mouthing others shop. Is it a good way to get earnings? Think about it.
