No, all the ISO system does is take the guesswork out of such things as
whether your 26 x 1/38 tire is an EA3, S1, S6 or whatever. There's no
safety issue involved, as the wrong size simply won't work (well, OK, I do
recall people trying to force a 590 tire onto a 597 rim and wondering why
they put all those holes into the tire with screwdrivers as they pried it
into place...).
So I agree that the ISO is a better system, but its lack of adoption
universally, or even a shop employee's not knowing about it, is not required
to get the right tire in your example. You could have asked for 27" or 700C
and had no problem whatsoever... pretty much anywhere you go.
If you wanted to pick a better example (of a place where the ISO system
works greatly to reduce confusion), try 26x1. That's where 559 (650c) vs
571 (mtn bike) is a really good thing to know. There's no way you can mix
up those tires (not possible to fit the mtn bike tire onto the 650 wheel,
and the other way around it's so loose that you can't possibly even think it
would work, much less get air into the tube long enough for you to jump on
the bike and go anywhere).

The hybrid bike pretty much killed off the remnants of the 27" world,
probably about the time you got sealed into that vacuum bag. It wasn't a
big deal, as better road bikes always had 700c wheels, and the
department-store versions (with 27" wheels) became extinct, in favor of
mountain bikes. Hybrids, for whatever reason, pretty much started off with
700c and things just carried on from there.

This is sounding more and more like a troll, but I'll answer anyway. Did
they have 700c-marked tires that you felt should have said 622? And did the
27" tubes really not have a 700c designation as well?

I wasn't condescending in the slightest.
I was however not really pleased that when it comes to
a matter of safety they don't know the means of ensuring
that the replacement part is the correct size.
