All our coffee is served with two shots by default. We're not some fancy coffee shop, just a motorway service station that makes coffee to go. We have some regulars who order a decaff with an extra shot. I explain thats going to have three shots total, and they're happy with it.

But I keep thinking, if you have three shots of decaff, isn't that going to be as strong as a normal coffee? Whats the point?

Please forgive my ignorance

Decaf coffee (or tea) will still have more than zero caffeine. Allowable amounts vary between US and EU, but multiple repetitions of the process are needed to achieve either 97% or 99.9% caffeine free respectively.

A single pass through a decaffeination process can result in leaving up to 20% of the original caffeine content.
