Interesting, I’ve always had the opposite problem - whatever I say they cut way too much off the top. Perhaps we should go together and order each other’s cuts?

I’m not sure I have anything helpful to say other than to suggest keep trying different places until you find one that listens?

This. Especially driving out of carparks.

I’ll give you a short answer as you’ve got a lot of detailed ones already: to a native British English speaker “six oh five a m” sounds completely normal. There are other ways to say it that sound equally normal.

Not a direct answer to the question but one thing not noted in other answers is in computing you often work at a higher precision than you need for your final answer as the errors tend to increase each time you do a mathematical operation.

In the world of reasonably powerful hardware (laptops, desktops, servers, smart phones etc.) we’d typically work with 64 bit floating point numbers which gives pi to 15 digits (I think, not at a real computer now so can’t check). because it’s simple to do so even though we don’t need the full precision.

I’m always tempted to get one but can’t quite justify the purchase. What difference does it make to your quality of life?

I’d suggest not calling anything out. People may well not hear exactly what you said and, even if they do, are unlikely to be able to process the information quickly enough. They’ll end up guessing what to do and that will often result in them doing the ‘wrong’ thing.

Could you provide a explanation for someone not in the US?

Yeah and you can systematically work through the various FODMAPs to figure out which ones cause you problems. It’s not that FODMAPs are all bad, it’s that there are groups of foods that you might be sensitive to.

This sounds like a great idea. What feed reader do you use? Are there ones specially for this or better suited to it or will any do?

I don’t like going outside but I do like dogs. One of the advantages of having a dog is that it means I do sometimes have to venture outside.
