Task: Question Answering
Input (English): I waited till the bartender refilled his cup , and then said to the twink " seriously ? I'll let you have it this time , but you should know that you just cost your bartender his tip for taking you first . " Before you all grab your torches and decide to run me out of the county , I DID tip my bartender . The former was only said to make a point to the little meth smacker that walked in front of me . Which brings me to the part of the evening the subject line refers to . 
Question: Why did I tip the bartender ?
Output (English): That's the nice thing to do .
