Well, each shop owner to the their own i guess, i can see why it would make life a lot easier for customers when we are busy....
But in business sense (which realistically.... you need when trying to run a shop

) it is a really irresponsible thing to do.
If someone is catching fish and on ladders and kickstools etc, customer or not, if they arent employed and had the training etc and something happens, they fall off the ladder or something, you are going to end up in trouble, with a lot of bills praying you dont get sued for something or another...
Not to ention, if other customers see someone who blatently doesnt work their catching their own fish... what kind of image does that give out? That you cant do the job yourself for whatever reason and that its ok for everyone to just help themselves...
I get asked by people if they can catch their own fish all the time and i wont have any of it...
There are exceptions, i have let someone help after i decided there was no way i was going to manage (though to be fair im right handed and it was in a sling and other staff were busy).
But there are always people who think they can do so much better because they've been keeping and catching fish for years longer than me and yet funny enough, they fail miserably and just end up upsetting my fish.
People forget that they might have kept fish longer than me but they dont spend every day catching lots of fish, probably got more experience in catching fish than someone keeping fish 5 times as long as me lol.
