anyone notice online casinos pay out differently depending on your location

Maybe it's just in my head, but it feels like my spins run cold whenever I'm not playing from home. Spent some time visiting family out of state and hit up my usual online haunts. Couldn't buy a win, and that's on games where I normally at least hold my own. Came back to my place and suddenly it's back to business as usual - same bets, same stakes, but better runs. I know randomness can be brutal, but the timing felt uncanny.

Also, I've seen a couple posts here and there about certain promos or bonuses being region-specific, like they know where you are and decide your luck for you. Maybe it's just variance being a cruel mistress, or maybe there's more behind the curtain. Has anybody else tracked their results and noticed patterns that match with where they're logging in from?
