You may have to be patient if you want them to see you (7)
I believe the answer is:
doctors
'you may have' is the definition.
I can't tell whether this definition defines the answer.
'to be patient if you want them to see you' is the wordplay.
I cannot really understand how this works, but
'to' is found in the answer.
'see' could be 'c' (the word for the letter, according to Chambers) and 'c' is located in the answer.
The remaining letters 'dors' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for doctors that I've seen before include "Alters" , "Cooks" , "fixes" , "Children's game staged around a hospital" , "Medical practitioners" .)
