How to confuse absolutely everybody.

The whole thing is a disaster!
Of all station announcements I heard - *none* stated the size of the
fee (all use "maximum cash fare", which does not say anything to
passengers), and most made some important omissions:
* Liverpool Street announcer does not say that this is for Oyster
Pay-As-You-Go* - she just says Oyster
* Stratford announcer does not say anything about Oyster at all (just
"if you don't touch in or touch out") and all with a very threatening
voice (IMHO)
* I think only DLR got everything correctly

Then again Stratford announcements should not be any indication - they
had big problems with automatic announcer during entire week (it
skipped names of several stations - "service to ... and ... arrives at
platform 10"). Finally they started using live person, and boy she's
fast! ("service to
Ilfordsevenkingromforgideaparkaroldwoodshenfilbile ricawickford and
southend victoria"). And with horrible accent.
