The Floyd Mayweather money hurricane touched down in L.A. last Tuesday night ... with the boxer throwing THOUSANDS of dollars in the air at a famous L.A. nudie bar -- and TMZ Sports has the footage.
Floyd hit up Sam's Hofbrau in Downtown L.A. -- the same place Dr. Conrad Murray allegedly hit right before he killed Michael Jackson back in 2009.
But sources connected to Floyd tell us ... it was a cheap night for the boxing superstar -- 'cause he only dropped around $30,000!!!!!
(In the past, Floyd's dropped more than $100k in one sitting at a strip club).
Check out the clip -- Floyd is throwing cash by the fist-full ... lotta women put through college that night.
