The LAG vs. the WSOP Wannabe - You make the call

[4_2_it]

The pugilists:
WSOP Wannabee - Dressed in full donk regalia, plays any ace and likes to emphasize the word "RRRAISSSE"
Age 23, ht 5'7", weight 156 lbs

LAG - Regular player in the room. Likes to talk and has mad post-flop skills, plays a lot of hands and likes table chatter
Age 47 ht 6'0" weight 185 lbs

The Main Event
WSOP Wannabee raises to $20 under the gun. One caller. LAG announces (in a rather loud voice) "I raise". LAG then matches WSOP Wannabee's bet and returns to his chip stack and brings out $60 more in a single motion.

LAG goes ballistic screaming that it was a string raise and since LAG said raise only the chips he held in his hand (Wannabee's original bet) was the full raise. Floor is called and determines that LAG's action was fine. Wannabee gets three more floor people over and after much bitching and moaning (and 6 lost minutes of playing time) the original floor decision stood.

Anyone disagree?
