Old Man McGee is an elderly man who is always angry and mumbles at himself. He has been playing the same (possibly broken) slot machine for five years without winning a single chip. He anticipates that the machine will some day break down and repay his questionable diligence provided that he, and only he, continuously plays that machine.
The slot machine can be repaired and give 50 XP (or more rarely, 100 XP), though it will always claim it is "still in sorry shape." Once fixed, it grants no further use.
With a high enough Luck, a coin can be inserted in the slot machine and pay out 500 chips, after which Old Man McGee will enter into an insulting dialogue and ask for the chips. All or half of the chips can be given, while keeping all chips will turn McGee hostile.
