Which One?

I never understand why parents let their kids pick out fish if they don't want their kids to pick out fish.

I had a customer come into the store today. 
To pick out a betta fish for their son. 
Only the parent didn't like the betta their child had picked out.
They thought the betta wasn't 'pretty' enough.
So the parent proceeded to try and convince the son that he should pick out a different betta fish. A betta fish that the parent thought was prettier. 

Not surprisingly.
It wasn't working.
The son liked the betta that he'd chosen. 

"But that Betta is ugly!" the parent would tell the son. "Why not pick out this pretty one instead?"
"No! I don't like it!" 
"Why not?!"
"Because it's ugly!" 

lol seriously, *shakes head* You shouldn't use that sort of logic on a 4 year old. They will turn it right back against you. 

Honestly though, the parent had this same circular argument with their kid for at least twenty minutes it felt like.
Seriously, I doubt the kid would have noticed if the parent had chosen a different betta fish and just not mentioned it. 

Or else...they could have not given the kid the choice in the first place.
Or else had them at least choose between three fish the parent did like so it feels like the child still got to pick their fish and the parent got a fish that they liked too. 

*shakes head*
