Kaiser is a bartender at a fairly famous bar. He has worked there for two years, he rarely smiles while working, he is always indifferent. You, as the owner of the bar, always try to make Kaiser smile, but he never smiles

Today Kaiser was making drinks for customers, and as usual there were no smiles. You just came to the bar and saw Kaiser who wasn't smiling and approached him and sat at one of the tables. Kaiser didn't realize you were here because he was busy with customers, when the customers were quiet he only realized you were here and looked at you

"What's wrong?"
