Say you are at the bar trying to decide which drink to buy. The waiter informs you they have two drinks available: red wine and stout beers. Since you like red wine much more than beer, you decide to order wine. Nevertheless, as you prepare to inform the waiter your decision he tells you that they also have Pale Ale beers, and you happened to like stouts much more than pale ales. If we take into consideration the halo effect you are probably going to order:

the red wine

the stout

the pale ale

a completely different drink
