card deposit ok but bank withdraw only after big win makes no sense

It drives me nuts how you can deposit instantly with a card, but the second you hit a solid win, suddenly you have to jump through hoops just to get your own money back. Why is it that card withdrawals turn into some big drama only after you actually win big? Small wins are fine, but if you want to cash out a larger amount, they suddenly insist on a bank transfer and ask for extra docs.

I don’t get the logic behind that. If the card was good enough to send them my cash, it should be good enough to send it back. Kinda kills the hype after a nice run on the slots when you have to wait days just for the payout to show up.
