There is an appeal on tv for funds for Sudan, and the doctor who is making the appeal tells us to text 70800 but he says 'text seventy eight hundred' - surely that would be 7800 and if anyone had trouble seeing the number on the screen they would text the wrong one. Or is it me?
I'm surprised no-one has suggested pronouncing the zeroes as if they were the fifteenth letter of the alphabet. You hear it all the time in adverts which tell you to call "oh-eight-hundred" instead of "zero-eight-hundred"
I take your point, Pedant, but no one says seventy eight hundred for seven thousand eight hundred. Up to nineteen hundred, yes, but over 20 we revert to thousands.
When I worked for Rail Enquiries this was a constant annoyance. We had to use the 24 hour clock. We used to get loads of complaints from people missing their trains because they had understood 22.11 as "twenty to eleven", i.e. 22.40.
