Here's a jerk move -- Carolina Panthers fullback Mike Tolbert paid an auto shop $3,900 IN COINS after feuding with the owner over the price of a new motor.
It all started when Tolbert went to Motion Lab Tuning to get some work done -- but MT says the place tried to rake him over the coals because "I'm a millionaire." He posted on Instagram calling the owner a crook.
But the shop has now fired back in a Facebook post (likely written by the owner) -- claiming Mike was the real problem .
