Irrationality

It's been very quiet of late as far as fliers' problems have been concerned. And I've been busy anyway: Dawn Vanden Plas and I have been on a base jumping masterclass in Norway. Dawn now has a flat nose and an irrational fear of road signs but I seem to have arrived home completely unscathed. Talking of irrational fears, how about this little number?

Dear Doreen
I have recently tried to make a donation on the Just Giving web site for the Air Ambulance people that scrape us off the hillside when we have an unintended meeting with the ground. I sent six whole pounds but I received a message back from them rejecting my money! This is what they said. "Dear Grant thank you for your recent donation but we are afraid that we have to reject any money that comes in amounts of six, seven, eight or nine British pounds. The reason for this is deep and personal for our CEO but just to say the date of 6/7/89 was a very bad day for him and involved a ladyboy and a bottle of bollinger 69. We can accept amounts in hon, hoo, hree, hor and hive pounds and ten pounds also. Thank you for your understanding."
Well Doreen I have a problem and no understanding to give them! You may have noticed that I wrote down the numbers between hon and hive so they sound like someone saying them in a strange way. This is because I have a phobia with those numbers (I was frightened as a child by an angry old lady shouting a nursery rhyme at me) and can't even bring myself to write them down, never mind send those amounts to a charity web site. I have no problem with the number ten but I'll be buggered if I'm giving the sods that much money. Any suggestions?
Yours, Grant Footcushion

Dear Grant
I rue the day that most of Europe went and got themselves embroiled in this silly Euro business. I don't say I didn't tell them but look at them now. A dozen years ago you could have sent them 2000 Spanish Pesetas or Greek Drachmas and everyone would be happy. As it is I can't see a way out. If you send them a tenner and ask for three - sorry, I mean hree or hor - pounds back you'll still have the problem of dealing with the change. Unless you send them 50p twelve times perhaps. 
I hope this helps, Doreen
