does using bonus money first make withdraw reviews take longer

Every time I’ve ended up using bonus money, I swear my withdrawal takes an extra day or two to clear, compared to when I just stick to my own cash. It’s gotten to the point where I wonder if the casino is purposely scrutinizing these withdrawals more or if I’m just paranoid. I mean, I get that they have to check wagering requirements and all, but sometimes the review drags on way longer than feels reasonable.

What’s weird is it doesn't always happen. Sometimes bonus play flies through without issue, but other times, they ask for extra documents or re-verify everything. Is it just luck of the draw, or are they digging deeper into bonus players? I’m not a conspiracy guy, but I do play a lot of blackjack with bonus funds, which maybe draws their eye. Just curious what everyone else sees with this.
