Drinks Are On The House!

Note
This is a timed quest, although the timing is not very strict. Once you get all five patrons drunk, return to Sam before they sober up, or else you will have to repeat the steps again.

Steps

 * 1) Speak to Sam to receive several, as well as a free shot.
 * 2) There will be five NPCs in the bar, highlighted in red or yellow. Click on them repeatedly to give them beer and make them drunk. When you run out of drinks, return to Sam for a free refill.
 * 3) Speak to Sam.
 * 4) For the next round, repeat exactly what you did before. Sam gives you another drink, so you will be even more drunk than before.
 * 5) Return to Sam.

Rewards

 * Your choice of:
 * 5 x Beer Token
 * 5 x Beer Token
