Why is Shannon Tweed annoyed with Gene Simmons?

Because their kids have left for college and when they(they kids) both finally get a chance to have a dinner with their parents, Gene doesn't show up because he's making a business deal. At his business deals there's almost a guarantee there will be bimbos. Shannon caught a picture of him leaving with these bimbos and she's mad because he ditched this dinner date with their kids for a stupid business deal with these random girls and she's tired of it ALWAYS happening...
