Why Sushi King promoted RM 2 Sushi?

Yes kiddys its me again, the day the teacher gets shited on, posting to say I had a sushi supper.

Yesterday I went to Tesco because my mom said Sushi King was running a promo: 2 bucks sushi. So, there we were outside the place marveling at how stupid ridiculously long the queue was. And I suggested we didn't wait 50 years for 2 bucks sushi so we had KFC. After that the queue was still darn long so we went shopping. Then when we came back the queue wasn't that long and we waited. Soon, we were having a sushi supper.

Now I'm wondering why such a promo was happening. Is it because Sushi King infected its rice and wants to turn us all into zombies? Or its just running a promo to boost sales? Either way I still hoping the teacher gets rabies.
