So, although there are international chain stores, cheap CDs and some good Bohemian crystal on offer, Prague's wholesale embrace of westernisation has made shopping for local items - in my case, a winter hat - difficult. At the Klobouky hatters on Wenceslas Square, a substantial lady with a fag hanging from her mouth dumped a pair of mink hats in front of me, and then scowled when I politely declined them. And at the Kotva department store a succession of bored young assistants rolled their eyes heavenwards and hooked thumbs over their shoulders, directing me to a tatty display of homburgs and top hats. Behind the façade of tourist-friendly Prague, some Soviet-style habits still die hard.
