Fork in right hand unless the meal is something (steak, for example) that necessitates a knife.
At which point knife in right hand and fork in left.
(I do use left retrieve for spin cast and right for baitcast).
This discussion reminds me of a story and warning to not overthink things.
The whole town gathered at the square one Saturday afternoon. Seems Mr. Hodges' beard had finally grown long enough that the fella from the Guinness Book of World Records was coming to measure and possibly award a world record.
After all was said and done, Mr. Hodges did in fact have the longest beard.
At the conclusion of the press conference, a final call was made to ask if anyone had anything else to ask..
One little boy stuck up his hand and asked : "Do you sleep with your beard under or on top of the covers?"
Mr. Hodges said he wasn't sure, but that he'd let the little boy know once he decided..
Mr. Hodges never got another good night of sleep....
