Flawless male logic

[LONDONER]

Woman: Do you drink beer?
Man: Yes
Woman: How many beers a day?
Man: Usually about three
Woman: How much do you pay per beer?
Man: $5.00 which includes a tip.
Woman: And how long have you been drinking?
Man: About 20 years, I suppose
Woman: So a beer costs $5 and you have three beers a day which puts your spending each month at $450. In one year, it would be approximately $5400 correct?
Man: Correct
Woman: If in 1 year you spend $5400, not accounting for inflation, the past 20 years puts your spending at $108,000 correct?
Man: Correct
Woman: Do you know how much that would be worth today if you didn't drink so much beer?
Man: No
Woman: You could have put that money in a step-up interest savings account.
Man: And?
Woman: After accounting for compound interest for the past 20 years, you could have now bought your own private airplane?

Man: Do you drink beer?
Woman: No.
Man: Where’s your airplane?
