I'm referring to things like

• being shortchanged, or overcharged by a few bucks and letting it slide
• finding a better deal after your purchase and not bothering to return and re-buy
• buying things at regular price instead of always waiting for a sale
• Parking where it's convenient even if it's paid rather than park a few blocks away for free
• Taking the 407/Uber
• Booking a more expensive direct flight vs cheaper flight with connections
• Any other examples you can think of
