I called one on myself Wednesday night.....the serve was a service winner(not returnable)
Our opponents said don't worry about it take the point, I said 2nd serve - it was blatant....
As for calling it against opponents I would only do so after multiple warnings and if the server was a serve and volley player and was gaining a clear advantage from the repeated violations....
Otherwise I would let the friendly recreational league match go on....most of the players in my mixed league foot fault a lot.....
It is a tough call tho, good thread.
