QC issues from manufacturers for NIB pins, it just seems like it's getting worse by each new release.

Taking deposits for games...
Not producing games for 2 years, not getting proper UL for shipping games.

No customer service for a 8 to 15k purchase.

Balls that come with NIB games that are rusted and pitted right out of the pack

How about a change machine that is out of order?

People buying (specifically preordering) games they've never seen or played based on theme

That all new pins don’t have headphone jacks by default.

I think not putting an auto-plunge in Star Wars Episode One was a pretty foolish blunder. I wouldn't say that it literally makes no sense, it's an understandable mistake to make, I suppose.

Some Data East games have two scoops for no reason, which I'd say is bad game design.

It doesn't make sense that the most recent code update for JJP PotC is still only available under the counter and isn't on the website yet.

It doesn't make sense to put pop bumpers in your game and not have them do anything interesting besides knock the ball away.

The upper flipper on Hotdoggin' doesn't make sense.

It doesn't make sense to base a pinball machine off of a movie that hasn't come out yet and might bomb. (although this changes somewhat if it's a movie that's part of an iconic franchise)

It doesn't make sense to give up the Legend of Zelda license to go after American Gladiators instead.

It doesn't make sense for a family entertainment center to have five pinball machines that are all in disrepair and unplayable when they could sell one and use the proceeds to hire someone to repair the rest.

It doesn't make sense for an operator to comment that they are planning on sending someone over to repair a broken pinball machine on pinballmap and then not do it for over a month.

It doesn't make sense for a player's heart to fill with loathing when the referee at a pinball tournament makes one singular call that they disagree with, but it happens. Too often.

It doesn't make sense that people complain so much.

Pinstadiums on a JJP! That's worse than new wipers on a broken windshield for me!

It doesn’t make sense that Stern’s fake/simulated knocker sounds nothing like a knocker.

It’s pretty annoying if you have RFM and you want to be able to swap in and out easily. Plus it’s strange when you’re in a Multiball and the game plops a ball into the shooter lane while you’re playing (I guess I could turn off MB ball save to avoid that).
