Timing is Everything

I try my hardest not to be opinionated but sometimes people say the silliest things and one is just plain obligated to respond!
Picture it...training hall...two experienced dog trainers...calmly discussing trainer A's current training problem. Their dog is having a problem with holding the dumbell. Trainer A describes how they have been trying to fix the problem (unsuccessfully obviously) through the use of a collar correction when the dog drops the dumbell. Trainer B (that would be me) wanting to be helpful, asks Trainer A if they had considered trying to use the clicker to shape a proper 'hold' to help the dog understand the specific behaviour they were asking for. Now wait for it...here comes the response that drove me into a tailspin.
Trainer A "Well no, I can't use the clicker because (drum roll please) I have BAD TIMING."
I stood flabbergasted (I am sure my mouth was open) trying to figure out how to respond positively to this comment. How could this experienced, well intentioned dog trainer, have 'bad timing'??? I mean how is it possible to train your dog well using any method if your timing sucks! Apparently to Trainer A, good timing was only a requirement if you were working with the clicker. Other methods of training (like collar corrections) did not require this skill. Now I know, some of you may be thinking that that is not what Trainer A really meant...but that is what they said.
I thought about it for a moment and then, in my most controlled voice and with a smile on my face asked this question..."So if you have bad timing, are you sure you are applying the collar correction at the precise moment in order to ensure that the dog understands how to avoid the correction in the future?"  My observation was that the answer should be no, as they had applied the same collar correction almost 10 times in this training session and the dog was still dropping the dumbell. Instead, Trainer A responded that "..oh they know what they did wrong, they are just being stubborn." At that precise moment the dog who had been listening intently to this conversation picked up the dumbell and literally spit it at her owner...Timing is everything.
