19. Odd Pricing. Why is that prices are like below (not clean, just odd)? An ABC reporter one time put exactly one gallon of gas at a gas station and gave $2.40 and asked for a change of 0.1 cent. There was no way that the gas station gave the reporter the 0.1 cent change.

Gas $2.339

Car $19,995

Membership fee $49

DVD $9.95

20. Anchoring. A fabulous restaurant presents wine lists like below:

Chateau Margaux $390

Chateau Palmer $190

Chateau Cost Destournel $90

Chateau Ponte Canet $49

Chateau Perriere $29

If you order Chateau Margaux, chances are that the restaurant does not have it. An actual business research found that which one was ordered most? Reason? Why is that Chateau Margaux is there on the list even though the restaurant has never had it?
