Person A asks person B out on a date. B accepts. A wants to impress B. A takes B out on the town to a nice restaurant. B is going through the date feeling unsure about everything, but giving A a try with an open mind. A tells B jokes and life stories. B continues with an open mind. Finally, A turns to B with the check for the dinner/drinks/tea and says, "With tip, your share is $25." B doesn't really want to be there in the first place and now has to pay $25 for the pleasure. A turns out to be a psycho. B never wants to see or hear from A again.
