Influence, Pizza, and an Expensive Taxi Ride

I read Influence by Robert Cialdini. Something unexpected happens and I have to take a taxi that costs a lot. I arrive late and think that I can buy a pizza instead of cooking dinner – the pizza seems less expensive than the taxi today. I remember the chapter about the merchant that sells an expensive suit first, then the shirt, so that it seems less expensive compared to the price of the suit. I give up on buying the pizza and cook dinner.
