Settling a dispute with a friend

Tonight I need the OOT forum's advice on settling a delicate dispute. My friend borrowed 20 dollars a few weeks ago to gamble with and lost it. When I asked him to pay it tonight he claims that he paid me the last time we saw each other (last thrusday). I remember bringing it up, but for the life of me I can't remember him giving me any cash. Nor did I notice any extra money on my wallet recently (Iusually carry about 40, so an extra twenty would be noticed.)

I am 100% positive that he still owes me, as he claims to be 100% positive that he does not.

Whats my play on this? A fight to the death with weapons has already been suggested. Any other option?

Hire a lawyer.

let the dispute simmer uncomfortably for many years, then bring it up awkwardly at some point down the road

tell him you believe him.
then ask if you can borrow $20.

lol

I would belittle him relentlessly untill he caves

ask him exactly where and when he gave you the money, see if it rings a bell for either of you.

if I paid someone $20 that I owed them, I would probably be able to tell them the specifics. "Remember, we were in the hall, right after we ran a train on that Holly chick, right?"

Tell him to go and buy a new friend with his $20

Next time you go to a bar, make sure he's really drunk, and put everything on a tab, work it out so he pays $20 more and you pay $20 less. This could be a tab spread out across several friends.

If he's a good friend and you both legitimately think you are right, split the difference and have him give you $10.
