Whenever I try to use the NATO codes, I invariably forget at least one of the letters I need to use. So it's all going happily "C for charlie, A for alpha, Dammit, what's P again? P for...umm....argh...papa!"

That's as a caller though, I've never worked in a position that requires me to take calls from the public. I've often been met with pleasant surprise by call-centre staff when I use it to clarify non-obvious spellings, and always request a read-back check.
