What are the advantages of such a piece of French plastic ?
Don't most places in France take Visa/M'cards ? I don't recall ever having a problem in my travels over the years.
N.B. this is a genuine query not a bit of "Frog Bashing"!
Many moons ago we took a Wessex to central France in support of the Sandhurst final exercise (that was great fun...one Wessex, two Lynx, a couple of Armee de l'air Pumas and a Gazelle all charging around at 30ft in the Massif Central - no beaches there of course!)
On the way back we had to pop into Le Touquet for fuel as the Freanch Air Force were closed for the weekend. They refused our Amex card so we hunted around and I finally had to get out my Access (as it was in those days).
We loaded just enough to get to Manston - it still cost over £400, but I made a little 'cos the accountants in SHQ were using a different exchange rate...
Now I'd carry everything if I could
