Waiting In Vegas

Tonight was a slow night so when I got sat a party of 8 I was excited to have something to do for 5 minutes.  When I went to the table I offered them water and began filling their water glasses. A couple of them wanted sodas so I rang them in and went to the bar to get them.  Right after I filled up the glasses with ice I see the party get up to leave.  I motion to them letting them know that I see them and that it’s OK.  The father walks up to me and says “My wife wants to eat somewhere else.  I’m sorry for the inconvenience.”  I assure him that it’s fine.  He apologized again and hands me $20.
