A Pretty Woman moment between my brother and I (after I had cleaned the house of the person he was housesitting for):

Me: So how much are you going to pay me?
Him: How much do you want?
Me: Well what were you thinking?
Him: I'll give you $50.
Me: Make it $60.
Him: Deal.
Me: $60 is good.
Him: I would have paid you $75.
