95% of my work is commercial.  I do some residential.  
Every day, I hear the same expression (or some slight variation)... "How about you come over to my house when you're finished".  
This is always meant as humorous, but I hear it 5 times a day.  What are some good retorts I can make?  Suggestions???  Remember, I hear this from all types, mostly women, young and old.  Maybe even an expression I can make to sell them.
Be creative
