In Switzerland, to visit even general family doctor it is normally required to make an appointment in advance that usually means to make a phone call. The chat with the receptionist is normally quite exhaustive, with them asking to describe all symptoms before they schedule the time. This conversation invariably must be done in German, even if the doctor can also speak English and often other languages when you finally get to the one.
Does the receptionist have the right to refuse the entry if the patient refuses the long conversation, restricting the talk to the fact that they are seeking medical attention? This is most likely to happen due language barrier but I can imagine it could be also other reasons.
P.S. The question is obviously about if the clinic can refuse medical help on the grounds that the visitor is not talking to receptionist. While there may be legitimate reasons to refuse the help, not all reasons are legitimate.
