Good roasters also usually have a decaf roast on the go. You can taste the difference, but if you’re just getting some random restaurant’s drip coffee, you’d probably just assume a bunch of things are off about it anyway, so “it’s secretly decaf” wouldn’t necessarily rank very high.
Decaf needs to be fresh and in bean form. I freeze them because they get bad much quicker due to porosity after the treatment to pull out the caffeine.
I also don’t think you would be able to tell the difference with good decaf.
