I get them to go out to the airport quite a lot and *002 rings a bell - but then I have been kown to buy a Klassenwechsel instead of an Anschlussbillette before and my German is fluent - I was obviously just having a particularly blonde moment Luckily the nice SBB lady who checked the tickets was having a 'nice' day and turned a blind eye once she'd had a good laugh at my expense. Ahem.
