If I had to point out a couple of things that bothered me about casinos, it'd be their withdrawal fees or minimum withdrawal amount being way too high compared to the rest of the casinos. There's always one or two casinos that would suddenly increase their minimum withdrawal out of nowhere and it's just a few extra steps that are unnecessary and can catch you off guard if you're a casual gambler. The fees of casinos can also catch you by surprise, and I remember it ate up a good chunk of my bankroll once because they had it on a fixed amount.
