I think you got fed a porky, Simmy.
During Lebron's first stint, his posse made some dumb mistakes, like not tipping well and acting like they were doing establishments favors by just being there. I witnessed it first hand and it was embarrassing because i knew a lot of the people who worked at, managed and owned the establishments. In Lebron's defense, i don't think he knew it was happening in many cases. Rich and Randy were always the one's responsible for picking up the tabs, etc.
That said, they've matured a lot. They are pretty smart cats and have learned from their many mistakes. Lebron hates bad PR. i can guarantee you this, that unless there was some incident or extraordinary set of circumstances - Lebron would NEVER refuse to pay a bill. That story sounds like a complete utter crock of shit. I'm also 99% certain that there hasn't been a single time in Cleveland where Lebron, Kevin and Kyrie have been in a bar/club together at the same time. Lebron is a homebody when he's home in Cleveland and avoids the bar/club scene like the plague. Those 3 just don't hang out together when they are in Cleveland. I could never see the 3 of them hanging at a club or bar here in town...not that they don't like each other, it's just not something i could ever see happening.
I can be one of Lebron's bigger critics and i could write a book of stories about him and his crew, but that one above sounds like pure fiction.
