No smile, no tip

Friday night after Michael's opening ceremonies, we went to have dinner. Doug takes the boys to the restroom, I am at the table and the server brings our drinks. He puts the boys sodas on the table, then hands me my ice tea. As he is handing it to me, he spills it. No big, it goes everywhere. He apologizes profusely, I help him wipe up the spill. He again, says he is so sorry and will bring me another one. My response to him was, "At least this time I did not melt." HE LOOKS AT ME BLANKLY. Am I the only one that thinks this is hilarious?
