What really makes things tricky is when people want to know what their local currency is worth - I know the French franc to the lire off by heart, but not what it's worth in the new money. I haven't yet had any Japanese groups and I'll be interested to see how they react.
Due to a shortage of small change some retailers have been giving back euro for euro and lire for lire. European tourists don't like that as they don't want to take a load of old lira home, and I don't want to get stuck with piles of lira notes as the February 28 deadlines approaches.
I find the number of coins - eight compared to the previous four - a nuisance and the smaller ones are quite hard to read.
Peoples' comments have been generally very positive, despite the teething problems they see it as a good thing for Europe as a whole. The Swiss are the only ones in trouble; tourists aren't going to appreciate having a euro that works all across the Continent and then having to swap it for Swiss Francs at the border.
I still believe that the euro will be a great asset for Italy, once we are all settled in to using it, and can help give us the boost to get over this difficult period for the tourist industry."
