At one point I was so infuriated that I would feel for the speaker and punch the pump so hard it would knock the speaker out of place (many pumps flimsy plastic.) I did that as many times as I could until the service company started gluing them in better. So I upped and ante by ripping open the front of the pump and tear the speaker out with my bear hands and smash it. Did that a bunch of times until the volumes were turned down.

I found out that's the help button and sometimes a clerk will come out and ask what I need help with and I tell that it stops the annoying noise coming from the pump.

That's pretty unhinged, but I'm glad there's someone out there vandalizing annoying pumps. It's important work, I think.

I’m reminded of the film Falling Down but I’ve given you an Internet point (upvote) for fighting the good fight. If good people do nothing, evil will triumph. In Ireland, we don’t (yet?) have such devilish instruments of torture but I imagine my cortisol levels would be through the roof if I had to deal with them.
