sometimes it all depends on the person – I said to someone at agility who was chastising her dog with a smack to the nose – why do you do that ??? she said well he isnt doing it properly is he ??? ??? i said well everytime you get it wrong should the agility class trainer smack you across the face then ??? or do you think you would feel more enthusiastic and interested in the whole event if she praised you when you got it right and forgave you when you got it wrong ???
However I did know the woman a little. I have been known to ask a complete stranger what the F&*k they thought they were doing. >:D but like others my mouth tended to go into overdrive before my brain. ::)
You obviously felt strongly about it and you did right to voice your concern.
