The ATC thing reminds me of a problem that my dad and I had when we flew
a Cessna 172, whose tail number was N466SR. Whenever we'd say "November
4 6 6 Sierra Romeo", there was a 50-50 chance that ground would reply to
"zero romeo" (our 'sierra' sounded like 'zero'). Whenever we used
"sugar romeo" as the phonetic, they always got it first time.

Ah phonetics
Sorry to tag on this post out of sequence.
The bottom line is communications. While it is true that by using a
*standard* alphabet one maximizes the probability of being understood,
in truth and in real practice, there are times when deviation may be
necessary.
First my qualifications: I was an air traffic controller for 30 years
and a pilot for some years before that, thus I have been intimately
familiar with the ICAO alphabet for nearly 40 years; using it on a
daily basis for most of that time. When everyone is on the same page
by official fiat, it is unusual to find the need for other than the
standard words.
However, in all the years I was DXing (on the way to Honor Roll), I
found that my particular callsign (N9AKE at the time) had a couple of
shortcomings in real world, difficult conditions. The "K" spoken as
"kilo" was often and easily lost in QSB or QRN. However, whenever I
used "kilowatt" there was a almost always complete understanding by
the other party, and I was able to successfully conclude my QSO.
The key here, however, is that "kilowatt" is almost universally
understood by hams, being a part of the argot of the pasttime. I doubt
I would have had more than a 50% success rate had I tried it at work.
Similarly, it is unlikely that substitutions others might try would
have as good a success rate unless they, too, were related to amateur
radio. If one were to try to use xenophobic, for example, most hams
(or other people) would choke on the word itself, since few are likely
to have even heard of it.
The argument made by someone that "kilowatt" could be confused for
"kilo" "watt" is specious, since in real communications, the use of
"kilowatt" is clearly a single word. If one were to use "kilo" and
"watt" as phonetics for discrete letters, they would be spoken clearly
and separately, whereas "kilowatt" is spoken almost as one syllable.
Context and common sense are somewhat of a determinant in successful
communications using phonetics. That is one reason why many DXers are
very successful using America, Brazil, Canada, Denmark, England,
France, Guatemala, etc., as phonetics. Hardly a DXer exists who
doesn't immediately recognize those words.
Finally we are not a commercial service, and public service aside, we
have no particular external requirement to get our communications
completed. There is no "officially sanctioned" alphabet that we are
required to use. Although, my skin crawls when I hear Bob say, "Broken
Old Bottle," the fact remains he is perfectly legal in doing so. In
amateur radio, success in communications is the only motive. If
"Boston London" (remember him?) gets it done regularly and reliably,
it's a good combination. If you don't want to have think one up, stick
with the ICAO (NATO) alphabet. For the vast majority of cases it's a
proven winner.
