Answer:
Sunk-cost fallacy.
Explanation:
The sunk-cost fallacy refers to the behavior done by the individuals when they continue such behavior because they already invested resources on it (time, money, effort).
In this example, <u>Les invested money on the megaphone of root beer,</u> he starts drinking it but <u>he becomes full, nevertheless he keeps drinking it </u>(even when his friend tells him he will get sick) <u>because he "bought it and not going to waste one drop of it"</u>
<u>Less continues drinking the root beer even though he's already full because he thinks he already invested money on buying it.</u>
