Ugh - I hate that tone! Negative, critical, controlling. And I do think - if you want things done in a certain way, do them yourself. But if someone else is kind enough to help, step back and let them do it their way.
Next time he does that, you may just want to hold up your hand, hand back the item to him and say - I'll let you do this your way - and walk out. I know you are hoping to save your M, but there's no need to tolerate being spoken to in that way.
FWIW...maybe I'm just a little feisty today....
