Well not wishing to cast doubt upon your anecdotal evidence, but  this is one of the big pieces of evidence used by the Anti-euro camp in the UK, allied with  a similar anecdotal memory of the change of currency from 1971, when the UK changed from £sd to new pence.  The exampled similar changes where all the shops rounded costs up that "Everyone" knows happened when coinage changed didn't appear in any financial statistics, no leap in Inflation rates happened due to this  change.

Any idiot can face a crisis - it's day to day living that wears you out.
