One of the best things about JD is that their is no person who will kick you out when you win too much.
Except the max bet gets changed if you win too much 
That actually works in your favour. You won a bunch and then the casino reduces the max bet so you can't lose it all back too quickly...
Also, it only happened once - the maximum player profit per roll was reduced from 1% of the total bankroll to 0.5% (via 0.25% for a couple of days) when it became clear that 1% was too high.
