Lazy Sit and Go day!

Day off today so tried a few sit and gos. Enjoyed the one I did last night and thought I would try my luck. Played 4 in total, all $5 stakes.

1st: 2nd
2nd: 6th
3rd: 1st
4th: 2nd

Had to rush my last one sadly, my friend came round to go to the pub. They do a tourni there every Wednesday. £5 rebuy. I've played there before and its pretty crazy but tonight was particularly crazy!
Bought in and had 3000 chips. Couple of hands in I'm up to 5000. Open up with KK. Under the gun raises me(very loose player) so I move all in, the guy next to me calls and so does the original raiser. Original Raiser shows 99 (fair enough) other guy shows J9!!! I'm thinking great!
flop comes 568, turn 2, river 7! THEY BOTH MAKE STRAIGHTS! Madness!
Anyway I rebought and topped up at the end of the rebuy period. Total stake £15

Get to the final 3 and the chip leader of all people decides to ask "Shall we split it?" He had about 45,000, 2nd had 40,000 I had 25,000. I was very happy, OBVIOUSLY! So we all end up getting £90 and turned cards for £10 to decided who gets the crown. I didn't but hey, well happy with the deal.

Now I need your advice, Do I put this £90/$180 into my bankroll or not?
Please leave comments to let me know what you think!

Later Guys!
