There are always exceptions:
Back about '77 I got hired to play upright bass in a bluegrass band that had landed a regular gig at a downtown club. St Paul after dark was pretty much dead, but after a couple of weeks wr were pretty much packing the place, overwhelming the limited wait staff. People were spending money faster than it could be rung up. So...
Instead of hiring second bartender and more waitresses, they fired us.
Turns out the place was actually owned by a large hotel chain, running it at a loss for tax purposes. When the band made it profitable they lost their write-off and closed up shop.
Things are not always what they seem...
That does make for a great story, but I'm sure it's also quite rare.
Couple weeks ago, the band I just started mixing played a really small bar. They are rock/country blend and typically pretty loud. All the guys dialed back on "stage" (on the floor in a corner) and the drummer softened up his playing. The bass player, who is a good friend of mine and has been playing since the 70's, said the stage sound that night was the best he's ever experienced.
At one point in the last set, when I had turned up just a bit, the owner came over to me and asked if it was a bit loud. Before I even had a chance to answer, he said, "Oh well, you'd know better than me." I asked the bar manager and she said he had asked her the same thing. Her reply to the owner was "hell no, these guys are great!"
