Hustled in home game last night?

[Python49]

Now i'm not much of a live game player and am probably too trusting when it comes to poker games ran by people my age since in my experience for games run through friends of friends theres never been anything shady. Last night however I went to a friend of a friend of a friends game and it was shady as hell.

I'm wondering how common this is in home games and if anyone else has had something happen like this because it totally caught me off guard, wasn't expecting it. The game we went to first of all it had this option where anyone involved in any hand all in before the turn could buy insurance to try to cut their losses. Basically for anyone not familiar it's a hustle where for example if you are ahead and your opponent has 2 outs, you are a 22:1 favorite, and the house was offering insurance at 14:1 odds so if you did get 2 outted they paid you back 14x whatever insurance you bought (basically like a bet). And clearly if your 22:1 against it hitting and making a bet that only returns 14:1 on your money you're losing in EV.

But even worse than this, they were raking pots sneakily with no structure or consistency at all. At first for a while I wasn't paying attention until I noticed $6 from my pot was raked and I said something about it. Now i'm damned sure home games should never be raking $6 out of pots when the most i've ever seen online was $5 and that was for high stakes and big pots. I thought by saying something about it, it would basically let him know that i'm aware of whats going on and it would stop. I should/could have just left but I thought these players were bad enough to stay and keep playing so long as I wasn't raked like that anymore.

Was hard to keep track of all the raking because alot of the time when id check my cards or turn my head, when i'd look back over at the dealer he was already turning around putting the rake into the bin. But when I left, my friend and I did deduced that based on the fact only one person won money and it was $250, and there were alot more losers... we basically estimated that about $600 had been lifted off the table in this 7 hour game or so.

Robbed? Hustled? Standard?
