I speak from bitter experience. I've had band members leave the stage to rescue SO's from a variety of persistent drunks and one couple got into a fight because he thought she was flirting too much with a patron. Another time, the drummers wife got roaring drunk and was ejected from the bar. He had to leave the gig and arrainge to have her taken home.
The list goes on; domestic disputes that go on between sets, lovey-dovey just off stage between sets, she had to leave because the show ran long and the babysitter charged extra after so many hours so I had to drive 40 miles out of my way to get HIM home, etc.
My wife comes to some of my gigs but she always comes with several friends and doesn't stay to the end. The support is nice but I still worry that something will go wrong. Since we also play in a couple of bands together. we have plenty of musical time together.
Still, as a general rule, I stand by LHAH. Over 40 years experience has shown me that, for me at least, it's the thing to do.
