Barney didn't have a problem picking up tabs. He had money, and wasn't terribly worried about saving it. Pft. Why bother when there would be more later? Even after the amount that he puts away for his mom, and the amount that he put away for Awesome the Nephew's college fund, he had enough. He did that because..duh. It was his mom. And nephew. And college was important. Please see that song inspired by Barney's (erroneous) retelling of his college days for the reasons why college was so important.
So he was paying Chip, and then turned to Red and gave a grin. Cufflinks were tugged at slightly. "Yeah it is! Like it?"
