The only wager I might make w/ a friend is who pays for a meal (if we're going out to eat).
But I don't find betting w/ friends appealing. I often pay for my friend's meals anyways because I have been pretty lucky with gambling; it's easy to spend the casino's money 😁.
I've encountered this kind of problem before playing Pragmaticplay and PlayNgo games, but I didn't lose my free spins bonus winnings because the bonus didn't disappear after refreshing the page.
I think betting with friends isn't a good idea because it can lead to arguments and hostility. Playing at online casinos and building good relationships with your friends is the right thing to do.
