fastfood

Once upon a time, Wrath was thinking craving for some fast food from a certain fast food chain K**. He entered the branch, thinking of visiting the washroom before making his order. He saw the yellow washing sign placed outside the washroom. As he was thinking of whether he should go find another washroom before coming back to make his purchase, he turned around and saw a ground staff waving him away rudely, signalling for him to make his way to a washroom elsewhere. Amazed at what he saw, he walked straight out of the outlet.

Have a guess at where he went to next.

The M fast food chain.
