Funny promo at Sakae Sushi

I was in The Curve waiting for a meeting and came across this banner at Sakae Sushi that said :

FREE SUPPER SET worth RM 15.90 with order of every Heineken…
I found this really weird. The food business is so competitive now that they are giving away food for drinks purchase?
Or is this because they wanna pull more beer drinkers into the restaurant. “Here, come and buy some beer. By the way, if you happen to be hungry – We’ll give you some food if you drink beer with us!”
Whichever it is, I think this is a crazy promotion!
