Not for me and I play a lot on Unibet.
Unibet for me usually verifies the cashout within the hour but I don't receive the money for anywhere between 24-48 hours. I guess it all depends what deposit method you use. I tend to use debit/credit cards and the timeframe for recieving funds after the withdrawal has been authorised seems pretty consistent to me across all sites.
At Rizk I'll have the withdrawal pending for 3 days +, basically until I contact chat and ask whats going on. then they authorise it. That's what bugs me, I just want it authorised so I know its on the way.
