Broken string Procedures

[pjr]

What do most people do after replacing a broken wire in the middle 
octaves of a home piano? Do you stretch it and leave it be?  Do you tune 
it sharp or on pitch?  Do you leave it muted or open?  Do you schedule a 
return visit to bring up the string?  If so, how soon?  Is a week too 
soon?  A month, or more?  Is one return visit enough?  If so, what 
percentage of your tuning fee do you charge for the return visit?  I 
would appreciate your ideas.
