Not 'PLEASE', please!!!

- Sorry, no longer at your service...
Dear colleague,
How many times have your students got the following simple statement wrong?
"Ich bitte Sie, mir die Dokumente zu mailen..." --> "I please you to mail me the documents."
Just in case this happens again - let your students (not under 16 years of age, please) have a look at this flyer picked up from a London phone box.
You shouldn't have any problem making it clear to your students what the verb to please really means...
BTW: The lady should be out of business by now anyway as the flyer was picked up in the early nineties... so no need to sue us for whatever...
