ploppy kicked out for "style of play"

Was playing recently and some poor lady was kicked out of a small casino for betting a big stack of red chips. She protested and demanded to know why she couldn't play blackjack anymore. She was jumping her bet around but it definitely wasn't at the right time. I found out she's a few thousand up on them recently. Just goes to show some casinos don't like winners and are overly paranoid. I can't believe they made this kind of mistake. It's kinda funny but I don't want to be next. Any tips on pocketing green chips or disguising your winnings? Should I continue to use a players card?
