DARIUS RUCKER picked up the tab for everyone eating at an IHOP in Mount Pleasant, South Carolina on Sunday morning.  He also left a “very generous” tip for the servers. 

He was eating there too . . . and when he was done he told the manager that he wanted to pay for everyone’s meal.  

The manager told WMBF-TV, quote, “It caused a lot of excitement.  We know him because he does come in quite often and we consider him a regular.”

The place was packed, but the manager wouldn’t reveal how much Darius shelled out.
