Worth repeating that this is not medical advice and the answer often depends on who you are.

An inconclusive account is useful if it stops the next person mistaking a story for a controlled comparison.

Personal experience, labelled as such, is exactly right here. Nobody is prescribing.

Photograph everything before you open it. Ten seconds, settles most disputes. Currently on SEPA transfer myself.

Ask for the longer appointment slot. Ten minutes is not enough for a complex history and pretending otherwise wastes both your time.

File early. The window is shorter than people think and it starts at the transaction. Same for me with DHL, unfortunately.
